Description

Resource to generate a mesh instance without buffers. For simple rendering pipelines that rely on shader programs only. A common use case for this is rendering a full-screen color or texture using a single triangle. The nap::RenderFaderComponent is set up this way and serves as a good example.

The following command invokes the vertex shader three times to render a single triangle. Logic for positioning the points is inside the vertex shader.

vkCmdDraw(commandBuffer, 3, 1, 0, 0);
