Using Stage 3D inside a Direct3D or OpenGL application

Before there was Stage 3D, I could simply capture the output of flash rendering engine with an in-place site and use it as a texture. But now, there is the Stage 3D which seems can't be rendered windowless... Is there a way to capture the output of…

While coding in low-level AGAL, do you need to create a new Program3D per Textures?

For example... If I'm developing an application that requires more than one texture in it (unique sprites, basically), do I need to call context3D.createProgram(); and assemble a new Program3D (with a VertexShaderAssembler and a…

What's the low-level code required to render a texture (BitmapData) to a Stage3D in 2D space?

I've looked at the following website for some information on writing AGAL to render Textures / Bitmaps to the Stage3D object: http://iflash3d.com/shaders/my-name-is-agal-i-come-from-adobe-1/ But it seems to cover more about how to create objects in…

AGAL: Calculating screen space position in fragment shader

Before I define my problem in more detail, I think I should begin by explaining how I've set everything up. Basically I have a simple plane mesh, defined as such (x, y, z, u, v): _vertices = Vector.([ -1, -1, 0, 0, 0, 1, -1, 0, 1,…

Adding glows to Stage3D objects

I'm making a Stage3D space game: www.sugarspook.com/darkmatters/demo.html, and I'd like to add 'glows' to some objects. Is there a way to do this solely in the AGAL shaders, or do I need to pre-render the glowing objects and 'blur' them?

I would like to create a wire frame effect using a shader program written in AGAL for Stage3D. I have been Googling and I understand that I can determine how close a pixel is to the edge of a triangle using barycentric coordinates (BC) passed into…

Can Stage3D draw objects behind all others, irrespective of actual distance?

I am making a 3D space game in Stage3D and would like a field of stars drawn behind ALL other objects. I think the problem I'm encountering is that the distances involved are very high. If I have the stars genuinely much farther than other objects I…
