Class SharedTexture

java.lang.Object
org.jzy3d.plot3d.rendering.textures.SharedTexture
All Implemented Interfaces:
IGLBindedResource
Direct Known Subclasses:
BufferedImageTexture
public class SharedTexture extends Object implements IGLBindedResource
An image stored in a 2D texture, that can be shared by several drawables. The texture is loaded in GPU through IPainter at mount, hence works with any native painter. A texture may be shared by drawables rendered by several charts, hence in several GL contexts : the texture is loaded once per painter. Image rows are stored from top to bottom, hence getCoords() gives a top coordinate of 0 and a bottom coordinate of 1.

      The texture name in the GL context of this painter, after loading it if not done yet.

    • hasMountedOnce

      public boolean hasMountedOnce()
      Description copied from interface: IGLBindedResource
      Return true if mount(...) has been called at least one time
      Specified by:
      hasMountedOnce in interface IGLBindedResource

      The image to store in the texture.
      Throws:
      IOException

    • rgba

      protected static ByteBuffer rgba(BufferedImage image)
      RGBA bytes of an image, rows ordered from top to bottom.
