The DrawModelInstancedIndirect method is a static member of the Sandbox.Graphics class. It is used to render multiple instances of a model using indirect drawing commands. This method leverages GPU buffers to determine the number of instances and their properties, allowing for efficient rendering of large numbers of objects.
To use DrawModelInstancedIndirect, you need to provide the following parameters:
model: The Sandbox.Model object that you want to render.buffer: A Sandbox.GpuBuffer that contains the indirect draw commands. This buffer should be properly set up with the necessary data for indirect drawing.bufferOffset: An int specifying the offset in the buffer where the draw commands start.attributes: A Sandbox.RenderAttributes object that contains additional rendering attributes, such as material properties or shader parameters.Ensure that the GPU buffer is correctly configured with the appropriate draw commands before calling this method.
// Example usage of DrawModelInstancedIndirect // Assume 'model' is a valid Sandbox.Model // 'gpuBuffer' is a properly configured Sandbox.GpuBuffer containing indirect draw commands // 'renderAttributes' is a configured Sandbox.RenderAttributes int bufferOffset = 0; // Draw the model instances using indirect drawing Graphics.DrawModelInstancedIndirect(model, gpuBuffer, bufferOffset, renderAttributes);
