The DrawModelInstanced method is used to render multiple instances of a 3D model efficiently. This method takes a model, a collection of transformation matrices, and rendering attributes to draw the model instances in a single draw call, which can significantly improve performance when rendering many identical objects.
To use the DrawModelInstanced method, you need to have a CommandList instance. You will also need a Model object that represents the 3D model you want to render, a Span<Transform> that contains the transformation matrices for each instance, and a RenderAttributes object that specifies additional rendering parameters.
Here is a step-by-step guide:
Model object that you want to render.Span<Transform> containing the transformation matrices for each instance of the model.RenderAttributes object to define rendering settings such as shaders, textures, and other parameters.DrawModelInstanced method on your CommandList instance, passing the model, transforms, and attributes as arguments.// Example usage of DrawModelInstanced // Assume commandList is an instance of CommandList // model is an instance of Model // transforms is a Span<Transform> containing transformation matrices // attributes is an instance of RenderAttributes commandList.DrawModelInstanced(model, transforms, attributes);
