    Hmmm...I wonder if, however, I will spend too much time processing the light source back buffer view to determine which fragments are in it. Even if the back buffer is low resolution it basically...

    Re: Lighting - Lioght Obstruction And Shadows

    Thanks for the posts but the issue isn't how to draw shadows...the issue is on which surface to draw them on.

    You will note that both the posts that you suggested all talk about where the shadow...

    Lighting - Lioght Obstruction And Shadows

    The WebGL examples at http://learningwebgl.com/blog/?p=1523 are really great but as far as I can tell all the lighting examples have one flaw: :cry:

    They don't implement any code that will...

    Re: Getting a pixel in webgl area

    When using ReadPixel, I found some problems when my Canvas was not square (i.e. when Canvas Width and Height did not match). As soon as they matched (regardless if they were a power of 2) Read Pixel...

    I am not sure the contents of your Camera code but typically Camera Views work backwards to how it appears they work. Normally the Camera is actually stationary and the rest of the world is shifted....
  14. Re: How to tell WebGL which size to show object in?

    It all depends on what the intention of the resize is.

    If you are looking to be able to resize the objects at will (i.e. you are going to be adjusting the object size dynamically) then...

  16. Re: Render texture to other webgl canvas element

    I am not sure why you are trying copy Canvas A to Canvas B. Why not just render your image to both Canvases? i.e. Rerender instead of copy?

    As far as I know you can't do that with requestAnimationFrame. This event just trips when the browser is refreshing its page but it not guranteed to happen at a set interval.

    You do not need to push and pop the Matrix unless you need to return back to the previous matrix (position).

    I'll give that a try.
