WebThere is only one kind of point primitive: GL_POINTS. This will cause OpenGL to interpret each individual vertex in the stream as a point. Points that have a Texture mapped onto them are often called "point sprites". Points are rasterized as screen-aligned squares of a given window-space size. WebThe usual place to call GL drawing is most often in OnPostRender () from a script attached to a camera, or inside an image effect function ( OnRenderImage ). using UnityEngine; public class ExampleClass : MonoBehaviour { // When added to an object, draws colored rays from the // transform position. public int lineCount = 100; public float ...
