The Draw method in the Sandbox.Graphics class is a static method used to render a set of vertices to the screen. This method is part of the rendering pipeline and allows you to specify a vertex buffer, material, and other rendering attributes to draw graphics primitives.
To use the Draw method, you need to provide the following parameters:
vertexBuffer: A GpuBuffer<T> containing the vertices to be drawn. This buffer should be filled with vertex data before calling this method.material: A Material object that defines the appearance of the drawn vertices. This includes shaders and textures.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 settings, such as transformation matrices and lighting parameters.primitiveType: A Graphics.PrimitiveType enum value that specifies the type of primitive to render, such as triangles, lines, or points.// Example usage of the Draw method
GpuBuffer<Vertex> vertexBuffer = new GpuBuffer<Vertex>(vertices);
Material material = new Material("myShader");
int startVertex = 0;
int vertexCount = vertices.Length;
RenderAttributes attributes = new RenderAttributes();
Graphics.PrimitiveType primitiveType = Graphics.PrimitiveType.TriangleList;
// Draw the vertices
Graphics.Draw(vertexBuffer, material, startVertex, vertexCount, attributes, primitiveType);
