Exposing objects ( THREE.WebGLObjects ) for faster target rendering

See original GitHub issue

I was looking into a faster way to render fbos into rendertarget using the renderBufferDirect threejs method. Got it working

this.renderer.setRenderTarget( prop.output );
this.renderer.objects.update( prop.mesh );
this.renderer.renderBufferDirect( this.camera, null, prop.mesh.geometry, prop.mesh.material, prop.mesh, null );

But it needs this object : https://github.com/mrdoob/three.js/blob/dev/src/renderers/WebGLRenderer.js#L286

to be exposed as a property of the renderer in order to update buffer attributes.

It could help to render objects and fbos immediately without using the whole render function. And also help to speed up post-processing effects method !

Is it worth exposing it ?

I wouldn’t expose it directly… Maybe build an API on top of it? renderer.getInternalProperty( value )?

@mrdoob I do not recommend to open up the renderer in the suggested way. The more internals are exposed (even via methods), the harder will it be to refactor and optimize the renderer in the future since users will rely on certain assumptions.

I think it’s better when above uses cases are realized when projects fork and modify the renderer according to their use cases.
