Hi, I am wondering how to draw a line on the glutSolid object for example I wan to draw a cream on a donut which I use as glutSolidTorus. Is that a way to do this?
Thanks.

Hi Dave,

I’ll take a look at it thanks. I’m using a theme I found on the web, but it shouldn’t take too much to modify.

Cheers,
Swiftless

Hello, I just wanted to let you know that i like this site and the content you are providing. Tutorials are very nice and to the point. The one thing i dont like is the web design width. You have to make it wider so that the various codes in tutorials dont show up weird. A little more view window will be nice. i am pretty sure most people interested on this website are high resolution monitors if the concern was to satisfy 800×600 people…

Hey Anna,

I’m confused as to why you are having trouble deleting shapes you have drawn. It is as simply as not calling the drawing code in your program.

You can use an if statement, so if something happens, draw the cube, or vice versa, if something happens, don’t draw the cube.

Or if you have a loop of shapes, skip the drawing for the specific cube you don’t want to draw.

Cheers,

Relying on libraries is a bad habit of mine
Despite sounding somewhat knowledgeable in my last post, I’m only beginning with GL.

My habits are still formed by basic experience with STL, which is “if it’s provided in a header, then it’s good, saves space, saves time, and is optimised.” That is generally true for STL. I don’t know about GLU’s performance or, more importantly, availability on different platforms.

Hi MatMar,

Yes, these are nice, but it means you have to rely on another library for basic shapes. Personally I recommend learning how to create or use a model loader as soon as possible, as you can only do so much with these shapes.

Actually you might want to have a look at some GLU routines.

gluNewQuadric
gluQuadricTexture
gluQuadricNormals
gluQuadricOrientation

Then you just use

gluSphere
gluCylinder
gluDisk
gluPartialDisk
