Multiple texture binding in PShader (for 2.0a7 or greater)?

in Core Library Questions • 1 year ago

Hello,

I have a question for the PShader API (maybe not if there is another interface available for this matter).

Is there any way to bind multiple textures to the shader loaded by PApplet.loadShader()?

I'd like to bind 3 or more textures in a shader at once (not a step by step sequence) for the uniform sampler2Ds,

but couldn't find any API with the PShader something like

PShader.set(String argument, PImage texture) or

PShader.set(String argument, PGraphics canvas)...

I found the PShader APIs suggests a great way to approach the GLSL, and

shader(PShader) or filter(PShader) works just fine so I loved to work with them. but,,

Well, I guess there might be language issues and reasons that the API designers didn't allow the ways like this.

Anyway,

Any suggestions for this matter?

(I'm on 2.0a7)

Thanks :)

I haven't tried a7 yet, but I glanced at some of the source. Take a look at line 334 of the PShader source.

Hello, the PShader.set(String, PImage) method didn't make either into 2.0a7 or 2.0a8, but it has been included recently into the API of PShader, so it will be available in the next release (probably the first beta).
