View ArticleHow to use a fragment shader on a PGraphics in Processing 2.0xx?
So far I've only gotten the filter(shader) method to work as a post-processing filter on the whole window. While the syntax pgraphics.filter(shader) is allowed, it doesn't seem to work. The method...

No need for begin/endShape, only begin/endDraw are necessary to draw on a PGraphics.

The filer(PShader) function should work with a PGraphics surface, as long as it is created as P2D or P3D:PShader edges;boolean applyFilter = true;PGraphics pg;void setup() { size(640, 360, P3D);...

I know there are approaches with double for loops to redo the Sphere-Command and make y sphere from rectangles and texture them somehow....but that 's too slow.the approach above used to work in...

Re : How to use a fragment shader on a PGraphics in Processing 2.0xx?
Thank you andres. It works! I also see now where the error was in my test code. I called pg.filter(shader) outside beginDraw-endDraw.Now that you have shown how to apply it correctly, it works fine.

Figured it out... wish this was somehow automatically included in Processing. Have to load the matrix (not sure if it is in each draw or just once in the setup). As described by Andres:You have to do...
View ArticleRe : Processing 2.0 - 1,000,000 points in OpenGL using Vertex Arrays
Thanks Andres, this looks like it fixed a few sketches for me. Is there anything we can do to simplify this - a new call to load this that is compatible? Does the matrix need to be loaded once, or is...
View ArticleRe : Processing 2.0 - 1,000,000 points in OpenGL using Vertex Arrays
You should load the matrices every time you change them: for example, if you call perspective() or ortho(), then you have to load the projection matrix. If you use camera() or any geometric...

Ok, so has a shader already been written for Processing that is called when these are used? If so, is it public where I could call it as oppose to doing my own. If not, doesn't Processing need it?...
