WebUpload an image. Upload your image that you would like to warp. 2. Warp the image. Warp the object using the warp grid. This will distort the placeholder along the defined curves. 3. Apply the warp. Upload another image that will be warped according to the warp grid generated in step 2. WebMulti-Draw Indirect Sample. Performance. This sample demonstrates how to use extensions to OpenGL to offload the CPU in generating rendering work when you have a large number of objects in a scene. The extensions and core features used are a subset of the features commonly known as 'AZDO' (For Approaching Zero Driver Overhead).
