VertexShader - parameter / matrix editions

I'm trying to implement a simple shader mask for my 2D engine and I have several problems to make it work.

Basically the shader takes two images and two matrices and tries remap back the position of vertices in the vertex sprites to the position of the local space mask then calculates the local uv coordinates for the mask, but I'm stuck with a few calculations base here.

Bug 1: Divisions of the core hardware vertex work not at all. That's why I put invertedMaskSize (which is 1.0 / 128,0) in the shader (but we already know that )

Bug 2: interpolated vars must be float4, float2 isn't possible (it's a pretty old bug as well)

I tried the following changes in the shader. The shader posted here, just try to display the uv coordinates resulting. No texture is used.

Case 1:

float4 ((vertexPos.x + halfMaskSize.x) = interpolatedMaskUV * invertedMaskSize.x, (vertexPoss.y + halfMaskSize.y) * invertedMaskSize.y, 0.0, 0.0);

The output is as follows: http://dev.nulldesign.de/plain_uvcoords.PNG Just like you expect! Perfect, we'll proceed.

Case 2:

Change the halfMaskSize and the invertedMaskSize to float2 and set the parameters in the form of two vectors of length two of course in ACE. Output: http://dev.nulldesign.de/float2_uvcoords.png

Case 3:

Masking test, the multiplication of matrices. First calculate the position of the global space of the vertex:

float4 worldSpacePos = float4 (vertexPos.x, vertexPos.y, 0.0, 1.0) * objectToClipSpaceTransform;

It maps then back to the local space of the mask:

float4 localMaskSpacePos = worldSpacePos * maskObjectToClipSpaceTransform;

And calculating the uv coords:

float4 ((localMaskSpacePos.x + halfMaskSize.x) = interpolatedMaskUV * invertedMaskSize.x, (localMaskSpacePos.y + halfMaskSize.y) * invertedMaskSize.y, 0.0, 0.0);

For the test, I put the maskObjectToClipSpaceTransform in contrast to the objectToClipSpaceTransform. In theory and on paper, it should work.

But, I think, something is happening in disorder and maybe the maskObjectToClipSpaceTransform is screwed in the shader, just as when I put the halfMaskSize and the invertedMaskSize to float2. The result is the following: http://dev.nulldesign.de/local_uvcoords.png and I don't have any idea how to resolve this...

< languageVersion: 1.0; >
texture core materials
<
namespace: "ND2D_Shader";
Seller: "nulldesign;
version: 1;
>
{
top of entry float2 uvCoord
<
ID: "PB3D_UV";
>;

top of entry float2 vertexPos
<
ID: "PB3D_POSITION";
>;

parameter float2 uvOffset;
parameter float4x4 objectToClipSpaceTransform;
parameter float4x4 maskObjectToClipSpaceTransform;

If the float2 value, strange things happen

parameter float4 halfMaskSize;
parameter float4 invertedMaskSize;

interpolated float4 interpolatedUV;
interpolated float4 interpolatedMaskUV;

Sub evaluateVertex()
{
not used in the current test...

interpolatedUV = float4 (uvCoord.x + uvOffset.x, uvCoord.y + uvOffset.y, 0.0, 0.0);

float4 worldSpacePos = float4 (vertexPos.x, vertexPos.y, 0.0, 1.0) * objectToClipSpaceTransform;

does not work as expected

float4 localMaskSpacePos = worldSpacePos * maskObjectToClipSpaceTransform;

float4 ((localMaskSpacePos.x + halfMaskSize.x) = interpolatedMaskUV * invertedMaskSize.x,)
(localMaskSpacePos.y + halfMaskSize.y) * invertedMaskSize.y,.
(0.0, 0.0);
}

image4 input textureImage;
image4 input textureMaskImage;
parameter of float4 color;

output float4 result;

Sub evaluateFragment()
{
just view the uv coords

result = float4 (interpolatedMaskUV.x, interpolatedMaskUV.y, 0.0, 1.0);

/*
texel sample = float4 (textureImage, float2 (interpolatedUV.x, interpolatedUV.y), PB3D_2D |) PB3D_MIPNEAREST | PB3D_CLAMP);
float4 texel2 = sample (textureMaskImage, float2 (interpolatedMaskUV.x, interpolatedMaskUV.y), PB3D_2D |) PB3D_MIPNEAREST | PB3D_CLAMP);

result = float4 (texel.r * color.r,)
Texel.g * color.g,.
Texel.b * color.b,.
Texel.a * color.a * texel2.a);
*/
}
}

I know that we are working with an old version of four months of pb3d and I hope that a new version will be out soon and maybe all these bugs that I have met are already solved, but if it isn't... Here is an another shader to fix

I just discovered another question when I worked through your example. If you have a parameter that is used by the kernel of vertex and a parameter that is used by the material evaluateVertex of the core function, they must have different names, even though they are supposed to be the same value. The particular setting that gave me the wrong is objectToClipSpaceTransform. I use it in my kernel of vertex standard, but it is also used in your example as an input to the function evaluateVertex.

We have not yet worked which is the right way to deal with this situation, for the moment, the work around is to make sure that the settings are two different names.

Adobe Photoshop Elements 12 modifies the EXIF DateTime parameter after editing and photo recording

Hello, I have a little problem with 12 elements. After I edit a photo and save it, elements changes the setting DateTime to the time the photo was recorded. Is there a way do not change this setting? Just to save the photo with a stock of EXIF metadata?

brian_oconner333 wrote:

In fact, it isn't. But I would like to know if changing this setting would affect other recognition apps (including mobile galleries) of the date that the photo was taken. I fear that some photos can be sorted incorrectly, especially in mobile applications.

I am running Windows 7. When I use Windows Explorer to look at the properties of the photo file, I can use the 'right click' and choose 'properties '. In the 'Détails' tab, look at the different dates, and you can see that the "date taken" is recorded in the Solution Explorer. This means that other software can share this information. What is misleading, it is that by default, i.e. "date taken" does not appear by default in Solution Explorer. Just like the keywords tags, you add this column to the screen. It is not clear in the Organizer, where you are shown the different dates in the catalog, but also the dates read from the image files...

Hello

You replicate the schema ogg11g tables and you are excluding the ogg11g of the user by using the parameter ogg11g of TRANLOGOPTIONS EXCLUDEUSER in the files of parameters extracted from both sides. The replication schema and schema admin GoldenGate should be different.

Please use a separate user for Oracle GoldenGate Admin and then try again option.

InDesign - recently created in InDesign vector images appear jagged.

If a vector object is simple, I'll create it in InDesign rather than placing a vector illustration Illustrator in InDesign. From a few hours, my vector graphics now have a slightly pixelated/jagged appearance on screen. I see my guy seems fluid that I converted to outlines.
I went under Edit-> Preferences-> display and enabled performance parameters with little chance.
Is attached a screenshot of my problem. The text in the editable text box and below, it is what is converted to text outlines. The right is a vector graphic, I developed in InDesign and was shredded not while I was developing (I would have noticed). Yet once, these objects are not placed and this graph was OK six hours ago.
Side note, I noticed the problem develop recently in Acrobat and was able to disable the parameter via Edit-> Preferences-> and Page display allowing the smooth line drawing and setting the smooth text to the monitor.
I'm writing this, I noticed that the problem goes away when I turn on an overview of overprinting, so I think my default vector lines (no stroke) make their appearance in staircase. It is not the end of the world and I can develop simple vector in Illustrator and then copy and paste over InDesign, it's simply boring. Any help is appreciated. Thank you.

It is only a screen problem, don't bother.

Drawing bitmap with exectfit

Hello
I have a movieclip with textfield placed on it. The size of my stage is 1003 X 560 pixels. When I open in a page html with exectfit and width 1366 and draw the bitmap of this movieclip. Then the text always right gotowards.
Please let me know if you have faced any issue like that.
Thank you

the draw() method of the copies class bitmapdata the non transformed object. If your movieclip transformed you will need to use the parameter matrix of the draw() method to draw the transformed movieclip.

Combining the BitmapData?

I am writing a slide show that takes an image at random from a Media RSS feed and creates a bitmap and adds it to the stage in a random scene position so that each new image on top of the last.
The actionscipt works very well, but after a while, the computer of memory and I get an ArgumentError: Error #2015: invalid BitmapData. error.
My thought was, instead of add children to the top of the child, I just add the new image of the original bitmap or maybe a copy of the bitmap and Exchange from the old to the new with each image newly added.
It is a possible solution and can someone help me with some ideas of code? All BitmapData.draw () examples of addig only one object at a time by the bitmap. I don't know if it is possible to add/merge/combine bitmaps.

Yes, it is certainly possible. I used this to combine up to 10,000 images bitmap in a single bitmap with great performance. What you want to do is make your original bitmap data to the size of the step to full, then when you draw in you use the parameter matrix of the draw method to place the copy.

Here are a few examples of code to show what I mean:

var a: BitmapData = new BitmapData (550,400);
var b:BitmapData = new BitmapData (50, 50, false, 0xFF0000);

var m:Matrix new matrix());
m.translate (50,50);

var c:Bitmap = new Bitmap (a);
addChild (c);

a.Draw (b, m);
m.translate (50,50);
a.Draw (b, m);

ALTER Sysdate
Hi all

I'll put up a new Oracle Architecture with two different instances of DB in the same machine, each of them represents a different region with a different time zone.

The main problem is that the two databases are running a PL/SQL application that uses Sysdate when inserting the current date in the tables. This is why we must find a way to change Sysdate in one of the databases to get the real time for each region.

There is no way to change sysdate to a database?

I was considering the following options, but none of them apply only to me.

Fix_date parameter.

Refresh the table after the creation of the new BO of Toplink
Hello

I have the following problem and I hope someone can help me. I use ADF11g/Taskflows with BOs TopLink-mapped (no ADF BC).

Consider the Taskflow (s) following:

the main activity is a (display) jsff page showing a table of BOs. From this point of view, two actions-defined results are called 'Edit' and 'create '. The edit action called an another Taskflow constisting of a pageFragment, showing the detailForm of the Soundtrack of data. This Taskflow has an input and output parameter (Soundtrack edit) and two are called "save" and "Cancel". Add Action calls a method called "createNewBO" first, and then calls the Taskflow mentioned also. Each Taskflow has ist own Bean managed in the pageFlowScope to work as a controller and DataControl to the TaskFlow and directly included views.

The edit action works fine. The action also add except that the table of the default activity of the first taskflow does not update after return from the second Taskflow. I tried to put the property of refreshment in the PageDef of all possible values, in combination with the RefreshCondition, but no combination works. I can do a manual refresh or change the sort then the new Soundtrack is shown in the table.

Is it possible to call a refresh of a jsff since a taskflow or I can force a refresh on entering the jsff?

I am really stuck and appreciate any help ;)

Friedrich
You can try this:

-on your taskflow diagram select the page that contains the table that you want to update, and add a Page parameter (from #{true} # {viewScope.refresh})
-in pageDef page add an invokeAction in executable files and that it points to methodAction which fills the iterator to update
-for newly created invokeAction, value refresh ifNeeded and condition of refreshment to #{viewScope.refresh}

This should refresh the iterator each loading of the page (fragment).

I hope this helps!

GetRow (Locals.TestMeasurements, Locals.Index), where Locals.Index is my rank specifier.

Any suggestions? It seems that it should exist in TestStand, but I can't find the function. Thank you

Locals.TestMeasurement [Locals.Index]

works for me. You may need to TestStand 2012 or later however.

Don't know which index you treat like the line. If this is the second you can do this:

Locals.TestMeasurement [0..] [Locals.Index]

Assuming that 0 is the lower limit for your first clue.

For more details on what it... average. See Help for the range for expressions operator (under operators / Other tab edition dialog box expression operators/functions).

Hope this helps,

The last version doesnot open new tab with google even after editing about: config

Until two days ago, that the new tab opened with Google.com. After the introduction of tiles in a new tab where the tiles with suggested sites are displayed, even after editing with subject: config, there is no change. Set in a new tab button suggested only the sites or blank page that crushes everything: config it seems

Firefox has tiles on the new tab from Firefox 13 page. But something has just changed: 41 Firefox no longer use the browser.newtab.url parameter in topic: config because he was constantly attacked by malware. From 41 of Firefox, you need an add-on to change the new tab page.

Here are a few options (I'm learning more all the time):
- If you are already using the "Restorer of classic theme" or "Tab Mix Plus" extension: There is an option somewhere (!) in his dialogues of the parameters to select another page in the new tab.
- If you want to use your new tab homepage: Try https://addons.mozilla.org/firefox/addon/new-tab-homepage/
- If you want to set another page or a completely blank page: Try https://addons.mozilla.org/firefox/addon/new-tab-override/
- If you want the cursor to move in a search box in the page: Try https://addons.mozilla.org/firefox/addon/custom-new-tab/
Use only one of these methods at the same time, otherwise there may be conflicts and dysfunctions.

Setting up substitute new tab and new tab custom

After installing one of these extensions, you must use the Options page to set the new desired tab page (instead of use subject: config).

Open the page modules using either:
- CTRL + SHIFT + a (Mac: Cmd + shift + a)
- "3-bar" menu button (or tools) > Add-ons
In the left column, click Extensions. Then on the side right, find the new tab replace or custom new tab and click on the Options button. (See first screenshot attached).

New tab Override

Depending on the size of your screen, you may need to scroll down to enter the address in the form. (See second screenshot attached). For example:
- (Default) page thumbnails = > subject: newtab
- Blank tab = > subject: empty
- Built-in Firefox homepage = > topic: welcome
- Any other page = > full URL of the page
Then tab or click this form field and you can test using Ctrl + t.

Custom new tab

It is easy to enter your favourite homepage address. If you check either of the boxes, the expansion will set the focus in the page as well, for example, the cursor will be in the Google search box. (See third screenshot attached). I had to leave Firefox and start it up again before new custom tab started working, but this may have been due to tests so many extensions back to back.

Success?
