Using the Molehill with Flash I wish to create a vertiex shader, to have one mesh transform into another, I have seen that it is possible with Flare, However I am unsure if that was using Stage3D, Can anyone give me any pointers in the use of shaders in AGAL as to how this might be done.

I understand the 'xyz' components of a vertex's position, but what does 'w' do? Could it be left as the same constant value all the time?
Example:
mov op.xyz, va0.xyz
mov op.w vc0.w
I've been struggling to write a Phong shader for my Molehill project. The problem is that the light seems to shift or move when the camera rotates. So I've been investigating what could possibly be wrong, by basically comparing my shader with the Phong shader written in GLSL. There's one thing I found that is kind of weird. In GLSL the output position in the vertex shader is ModelViewProjectionMatrix * Vertex, ok that is just fine.
HOWEVER, in Molehill the ModelViewProjectionMatrix has to be transposed so that it will render the vertex correctly to the screen. In GLSL that is not necessary.
How did I find that out? I created the Matrix3D modelViewProjection, I applied the ModelView to that matrix and then the Projection matrix. I tried to give the vertex shader that matrix and it displayed nothing until I transposed the modelViewProjection.
In GLSL this is not necessary, I could just say output.position = projection * modelview * vertex and it would be displayed correctly, I don't need to do transpose(projection * modelview * vertex).
So.. I'm wondering if there's something that I am not seeing here or is this a special part of Molehill that we just have to follow? Or could it be a bug in Molehill? I will create a new post tonight with my Phong shader and hope that someone sees what I may be doing wrong. But this is confusing me a lot at the moment and would like to know why the matrix has to be transposed.
I've mostly seen examples where a Matrix3D object is passed as a vertex constant register in AS3 to the Context3D object. But never seen a matrix in any other types of registers (temporary or attribute).Would there be any way to copy a Matrix vertex constant to a temporary register, and then manipulate individual fields of that Matrix temporary register (ex:for the rotation), with other supplied values (vertex attributes or other constants)

View 3 RepliesI'm trying to understand molehill and would like to multiple a vertex by two matrices, say:
output = theVertex * scaleMatrix * rotationMatrix
Im guessing my vertex shader would look something like:
"m44 vt0, va0, vc0
" +
"mul op, vt0, vc1
";
And i would set the matrices with
context3d.setProgramConstantsFromMatrix(Context3DProgramType.VERTEX, 0, scaleMatrix);
context3d.setProgramConstantsFromMatrix(Context3DProgramType.VERTEX, 1, rotationMatrix);
But its not working.Im aware that i could multiple the matrix before putting on the shader, but i am trying to understand AGAL.
If I make multiple draw calls for various Program3D instances, is there a way that I can reset or nullify the constants if I'm no longer using them in the next following Program3D assignment?
Is it even necessary that I do something like this?
//Nullify 'vc0' in the vertex shader:
context3D.setProgramConstantsFromVector("vertex", 0, null);

This is all runnig in the Flash Player and uses OpenGL on OS/X and Linux, and DirectX on Windows.
Where can I download the Molehill API / library from and what else do I need to get it running?
View 2 RepliesUsing Flash 11 RC1 with the new Molehill API, I would like to enable backface culling. The beta documentation is pretty vague, but the example implies Molehill wants front-facing triangles to wind counter-clockwise, which is pretty normal. But when my polygons wind counter-clockwise, I get the exact opposite behavior - in other words, it's as if contrary to its own examples Molehill expects front-facing triangles to wind clockwise. Since the documentation never explicitly states which winding is correct, I am stumped.
I don't want to just flip all my triangles around until it looks right before I am 100% on what Molehill actually wants, since that has a fair chance of hiding a fundamental misunderstanding. I am using simple perspective projection (a note regarding .transpose() below: because copyRawDataFrom expects data in column-major order, and I hated the way that looked in code, I decided to just enter it row-major and transpose the matrix afterwards

Here's a snippet of a pixel bender shader that I'm using in Flash:
parameter float2 srcSize
<
parameterType: "inputSize";
inputSizeName: "src";
>;
input image4 src;
The width and height of the source image are filled in correctly in the Pixel Bender Toolkit, but when I run this shader as a filter in Flash Player 10, the srcSize value is not automatically filled in.
I am retired and I am trying to study Flash, and I am practicing with the tutorial about Morphing text, every thing is ok, but it is too fast I can't read what it says.
View 2 RepliesI am fairly new to flash and I'm currently using CS4 to create shape tweens that morph from a shape (in my case an astroid, not to be confused with an asteroid) to text that I have broken apart into individual shapes. This works very well with the shape tweens; however, I would like to use symbols instead of shapes for my tween.
Naturally, I converted my shape and my broken apart text to symbols and then set up a motion tween. My research has told me that you cannot morph from one symbol to another using ANY tween, but this would not make sense to me.
Am I missing how to actually do this? If it is true that you cannot morph between symbols, then why on earth hasn't Adobe made a way to do this. If I need to substitute one shape for another in a flash video, and I have this shape in 100s of frames in the video, there is NO way to quickly find and replace those shapes, especially if you've duplicated the the several (20) times in each frame.
Few days ago I uploaded my flash face morphing application and now I'm thinking of writing an article about creature process.URL... anyone curious about how I made it?

View 1 RepliesIs there a way to render multiple vertex buffers in AS3?Right now I have two objects which I want to render, but the only way I can think to do it is to concatenate the raw vertex data (of both objects) and then set that (concatenated) vector as the vertex buffer.I would prefer to do this as 2 separate vertex buffers, but I don't know how to render from more than one vertex buffer.

I'm working through Dreamweaver fairly well, and I'm now wanted to import Flash buttons I've created myself into Dreamweaver for a website I'm currently building, and it's here that I'm finding the problem. I have been to the 'get URL Function', but it says something about needing to link to a web page?

We've got a green screened video playing in a flash movie over top of our html content.when the movie ends, flash uses external interface .api to call a javascript function which swaps the flash movie out with a 5 x 5 pixel flash movie (rewrites the <div>).this works and you can interact with the html content after the flash movie in all browsers except firefox.anyone know of any work-arounds or is there a better way of handling flash over html in this fashion?
