Hello everyone,
So basically, I’m trying to draw Mars in a 3D space, which I have to save to a PDF file. In order to do that more easily, I made a second project where I only make the texture which will overlay the sphere. It is looking how I want it to and I can copy this code to my original (3D) project without any problems. But when I want to save it to a PDF file (which I have to do because that’s the assignment), I just get a blank file and this error:
"texture() is not available with this renderer.
vertex(x, y, u, v) is not available with this renderer."
In order to simulate the exact same problem in the more simple code where I made the texture, I am using the P2D renderer. Just like expected, the same thing happens with the same error. I will be sharing this simplified code with you, because if we can solve the problem in this file, I think I can also solve it in my 3D file.
With only 1 month of programming experience so far, I really have no idea what to do anymore. If someone would be able to help me with this, that would be really appreciated.
