The DrawModelInstancedIndirect method is used to render multiple instances of a model using indirect drawing. This method leverages a GPU buffer to determine the number of instances to draw, allowing for efficient rendering of large numbers of instances without the need for CPU intervention.
To use DrawModelInstancedIndirect, you need to provide a Model that you want to render, a GpuBuffer that contains the indirect draw arguments, an integer bufferOffset to specify the offset in the buffer where the draw arguments start, and RenderAttributes to define additional rendering parameters.
// Example usage of DrawModelInstancedIndirect
var commandList = new CommandList();
var model = new Model("path/to/model");
var gpuBuffer = new GpuBuffer(); // Assume this buffer is properly initialized with draw arguments
int bufferOffset = 0;
var renderAttributes = new RenderAttributes();
// Draw the model instances
commandList.DrawModelInstancedIndirect(model, gpuBuffer, bufferOffset, renderAttributes);
