I am trying to use the OpenGL plugin for eclipse. I have the quads drawing
correctly but I cannot seem to get textures working. I am specifically
interested in created a 3d globe. Has anyone been able to get textures
working? If so please send me sample code. I am already doing something
like:
// in my initGL
source = getTextureImageData(in);
GL.glGenTextures(1, textures);
GL.glBindTexture(GL.GL_TEXTURE_2D, textures[0]);
GL.glPixelStorei(GL.GL_UNPACK_ALIGNMENT, 1);
GL.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_WRAP_S,GL.GL_REPEAT);
GL.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_WRAP_T,GL.GL_REPEAT);
GL.glTexParameteri(GL.GL_TEXTURE_2D,
GL.GL_TEXTURE_MAG_FILTER,GL.GL_LINEAR);
GL.glTexParameteri(GL.GL_TEXTURE_2D,
GL.GL_TEXTURE_MIN_FILTER,GL.GL_LINEAR);
GL.glTexEnvf(GL.GL_TEXTURE_ENV, GL.GL_TEXTURE_ENV_MODE, GL.GL_MODULATE);
GLU.gluBuild2DMipmaps(GL.GL_TEXTURE_2D, texFormat, source.width,
source.height, texFormat, GL.GL_UNSIGNED_BYTE, source.data);
// in my drawScene
GL.glEnable(GL.GL_TEXTURE_2D);
GL.glBindTexture(GL.GL_TEXTURE_2D, textures[0]);
// drawing code
...
GL.glDisable(GL.GL_TEXTURE_2D);

John,
The examples plugin demonstrates a texture in use, see
http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/plat form-swt-home/opengl/org.eclipse.swt.opengl.examples_3.1.0.z ip .
