GL11.GL_SPHERE_MAP 1.15

[M1ntcraft3r]

Hi,

 

I'd like to use SPHERE_MAP from GL11 to draw a sphere with given radius around a block position.

I have been using GL_QUADS successfully to draw quads and planes but was hoping the SPHERE_MAP would be able to draw spheres for me.

However, I have not had any luck with it...

 

 

When using the QUADS, I can draw a plane by giving the 4 corners such as:

 

        bufferBuilder.pos(center.getX() + 1, center.getY() - diameter / 2, center.getZ()).endVertex();
        bufferBuilder.pos(center.getX() + 1, center.getY() - diameter / 2, center.getZ() + 1).endVertex();
        bufferBuilder.pos(center.getX(), center.getY() - diameter / 2, center.getZ() + 1).endVertex();
        bufferBuilder.pos(center.getX(), center.getY() - diameter / 2, center.getZ()).endVertex();

 

but how do I use the SPHERE_MAP

 

TIA

GL_SPHERE_MAP is used for spherical environmental reflection textures, to my understanding; they have nothing to do with actually drawing spheres.

Ah, OK, that makes some sense..

 

Any idea how I could go about drawing a sphere in Minecraft?
