*
* GPUComputationRenderer, based on SimulationRenderer by zz85
*
* The GPUComputationRenderer uses the concept of variables. These variables are RGBA float textures that hold 4 floats
* for each compute element (texel)
*
* Each variable has a fragment shader that defines the computation made to obtain the variable in question.
* You can use as many variables you need, and make dependencies so you can use textures of other variables in the shader
* (the sampler uniforms are added automatically) Most of the variables will need themselves as dependency.
*
* The renderer has actually two render targets per variable, to make ping-pong. Textures from the current frame are used
* as inputs to render the textures of the next frame.
*
* The render targets of the variables can be used as input textures for your visualization shaders.
*
* Variable names should be valid identifiers and should not collide with THREE GLSL used identifiers.
* a common approach could be to use 'texture' prefixing the variable name; i.e texturePosition, textureVelocity...
*
* The size of the computation (sizeX * sizeY) is defined as 'resolution' automatically in the shader. For example:
* #DEFINE resolution vec2( 1024.0, 1024.0 )
*
* -------------
*
* Basic use:
*
* // Initialization...
*
* // Create computation renderer
* var gpuCompute = new GPUComputationRenderer( 1024, 1024, renderer );
*
* // Create initial state float textures
* var pos0 = gpuCompute.createTexture();
* var vel0 = gpuCompute.createTexture();
* // and fill in here the texture data...
*
* // Add texture variables
* var velVar = gpuCompute.addVariable( "textureVelocity", fragmentShaderVel, pos0 );
* var posVar = gpuCompute.addVariable( "texturePosition", fragmentShaderPos, vel0 );
*
* // Add variable dependencies
* gpuCompute.setVariableDependencies( velVar, [ velVar, posVar ] );
* gpuCompute.setVariableDependencies( posVar, [ velVar, posVar ] );
*
* // Add custom uniforms
* velVar.material.uniforms.time = { value: 0.0 };
*
* // Check for completeness
* var error = gpuCompute.init();
* if ( error !== null ) {
* console.error( error );
* }
*
*
* // In each frame...
*
* // Compute!
* gpuCompute.compute();
*
* // Update texture uniforms in your visualization materials with the gpu renderer output
* myMaterial.uniforms.myTexture.value = gpuCompute.getCurrentRenderTarget( posVar ).texture;
*
* // Do your rendering
* renderer.render( myScene, myCamera );
*
* -------------
*
* Also, you can use utility functions to create ShaderMaterial and perform computations (rendering between textures)
* Note that the shaders can have multiple input textures.
*
* var myFilter1 = gpuCompute.createShaderMaterial( myFilterFragmentShader1, { theTexture: { value: null } } );
* var myFilter2 = gpuCompute.createShaderMaterial( myFilterFragmentShader2, { theTexture: { value: null } } );
*
* var inputTexture = gpuCompute.createTexture();
*
* // Fill in here inputTexture...
*
* myFilter1.uniforms.theTexture.value = inputTexture;
*
* var myRenderTarget = gpuCompute.createRenderTarget();
* myFilter2.uniforms.theTexture.value = myRenderTarget.texture;
*
* var outputRenderTarget = gpuCompute.createRenderTarget();
*
* // Now use the output texture where you want:
* myMaterial.uniforms.map.value = outputRenderTarget.texture;
*
* // And compute each frame, before rendering to screen:
* gpuCompute.doRenderTarget( myFilter1, myRenderTarget );
* gpuCompute.doRenderTarget( myFilter2, outputRenderTarget );
*
*
*
* @param {int} sizeX Computation problem size is always 2d: sizeX * sizeY elements.
* @param {int} sizeY Computation problem size is always 2d: sizeX * sizeY elements.
* @param {WebGLRenderer} renderer The renderer
