problem adding bumpmap to textured gluSphere in JOGL
- by ChocoMan
I currently have one texture on a gluSphere that represents the Earth being displayed perfectly, but having trouble figuring out how to implement a bumpmap as well.
The bumpmap resides in "res/planet/earth/earthbump1k.jpg".Here is the code I have for the regular texture:
gl.glTranslatef(xPath, 0, yPath + zPos);
gl.glColor3f(1.0f, 1.0f, 1.0f); // base color for earth
earthGluSphere = glu.gluNewQuadric();
colorTexture.enable(); // enable texture
colorTexture.bind(); // bind texture
// draw sphere...
glu.gluDeleteQuadric(earthGluSphere);
colorTexture.disable();
// texturing
public void loadPlanetTexture(GL2 gl)
{
InputStream colorMap = null;
try
{
colorMap = new FileInputStream("res/planet/earth/earthmap1k.jpg");
TextureData data = TextureIO.newTextureData(colorMap, false, null);
colorTexture = TextureIO.newTexture(data);
colorTexture.getImageTexCoords();
colorTexture.setTexParameteri(GL2.GL_TEXTURE_MAG_FILTER, GL2.GL_LINEAR);
colorTexture.setTexParameteri(GL2.GL_TEXTURE_MIN_FILTER, GL2.GL_NEAREST);
colorMap.close();
}
catch(IOException e)
{
e.printStackTrace();
System.exit(1);
}
// Set material properties
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_MAG_FILTER, GL2.GL_LINEAR);
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_MIN_FILTER, GL2.GL_NEAREST);
colorTexture.setTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_WRAP_S);
colorTexture.setTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_WRAP_T);
}
How would I add the bumpmap as well to the same gluSphere?
