The Draw method in the CommandList class is used to render a set of vertices from a specified vertex buffer using a given material. This method is essential for drawing non-indexed geometry in a rendering pipeline.
The Draw method in the CommandList class is used to render a set of vertices from a specified vertex buffer using a given material. This method is essential for drawing non-indexed geometry in a rendering pipeline.
To use the Draw method, you need to provide the following parameters:
vertexBuffer: A GpuBuffer<T> containing the vertices to be drawn. The type T should match the vertex structure used in your shader.material: A Material object that defines the shader and rendering state to be used for drawing the vertices.startVertex: An int specifying the starting index in the vertex buffer from which to begin drawing.vertexCount: An int indicating the number of vertices to draw from the vertex buffer.attributes: A RenderAttributes object that provides additional rendering parameters and settings.primitiveType: A Graphics.PrimitiveType enum value that specifies the type of primitive to render (e.g., triangles, lines).// Example usage of the Draw method var commandList = new CommandList(); var vertexBuffer = new GpuBuffer<Vertex>(); // Assume Vertex is a predefined struct var material = new Material(); int startVertex = 0; int vertexCount = 100; var attributes = new RenderAttributes(); var primitiveType = Graphics.PrimitiveType.TriangleList; commandList.Draw(vertexBuffer, material, startVertex, vertexCount, attributes, primitiveType);
