Class QuadRender

An object that renders a quad using a Shader.

Note: QuadRender does not modify render states. Before calling QuadRender#render, you should set up the required states using GraphicsDevice#setDrawStates, or the individual setters (GraphicsDevice#setBlendState, GraphicsDevice#setCullMode, GraphicsDevice#setFrontFace, GraphicsDevice#setDepthState, GraphicsDevice#setStencilState). Otherwise previously set states will be used.

Example:

const shader = pc.ShaderUtils.createShader(app.graphicsDevice, {
    uniqueName: 'MyShader',
    attributes: { aPosition: SEMANTIC_POSITION },
    vertexGLSL: '// vertex shader code',
    fragmentGLSL: '// fragment shader code'
});
const quad = new QuadRender(shader);

// Set up render states before rendering (defaults are suitable for full-screen quads)
app.graphicsDevice.setDrawStates();

quad.render();
quad.destroy();
