Add copy and clone methods in Program class #155

Open RAX7 opened 2 years ago

RAX7 commented 2 years ago

In some cases it is necessary to create programs with the same shader code but different uniforms (eg texture or color). The clone method creates a shallow copy of Program class. Copies all properties by reference except the uniforms. If uniform value has a clone method (eg Vec2, Mat4), it will be used, otherwise (eg Texture) the value is copied by reference.

what is the difference by using the Program in the multiple Mesh you need and then change Mesh.program.uniforms.uTexture by hand ? Or am I mission something

eXponenta commented 1 year ago

@Nam-Hai Yep, clone doings fullcopy of programm include a uniforms state. You should know all copies of programm if you want to change uniforms state for all of them.

This is why i did proposal use a Material wrapper that will have shared program/material state.
