How to query OpenGL to get the enabled bit for all lights..?

capturevision

Hello,

I'm looking for a way to query OPENGL to know if a certain light is enabled or not (via glGetBooleanv, glIsEnabled, or.. something else)..

I've seen the docs but no luck for the moment..

Any help would be greatly appreciated.

Hi, there is no function to check if lights are enabled or not. Processing 2.0 uses OpenGL's programmable pipeline, which doesn't have built-in lighting. Lights have to be defined manually with your own uniforms. Processing tries to simplify this a bit by automatically filling some pre-defined uniforms (lightCount, lightPosition, etc.) according to the values you set in the sketch code using pointLight(), spotLight(), etc.

Thanks Andres,

I was talking raw OPEN GL, not P5, should have mentioned it. Found my way around with gl.glIsEnabled(GL2.GL_LIGHTx);
