LÖVE

I'm sorry if this is ignorant, but LÖVE says my graphics card does not support pixel effects, and when I googled it it seemed it does...
I have an iMac with a radeon x1600

Raycast is too slow. Look at shader toy demos, they are fast and pretty.

which shader toy demo's?

All 3D demos: Apple, 704, etc...

Quick question on conditional statements in GLSL.
How do you put multiple conditions in a single 'if' statement (not familiar with C++).
Can get nested ifs to work but not multi-conditional (see attachment).

You'd use && for and and || for or.
I would, however, like to tell you that conditionals are very inefficient in shaders.

Thanks bartbes.
Appears I was just screwing up some of the syntax.
Have to do some more thinking as to how to avoid the conditionals.
Tried using sequential application of shaders but got different results then with conditionals.
Dumb question - where is a source for functions available in GSGL language used by shaders?

Here is a GLSL reference. It is also linked in the wiki at love.graphics.newPixelEffect.

Thank you vrid.
Should have found this info on the WIKI but still quite new here.

A simple shader.
Image just a place holder.
Would like a transparent ball shader.
Anyone have one?
