I am a new guy here,and I have lots of problems,here is one of them.Is there some kind people can help me?
Post what you got so far (code) so we can help you
Tell us exactly what you need!
Thank you for your reply.I want to draw several primitives,including cylinder,cone and spherical cap,and to add texture to them.Cylinder and cone is ok,but I can’t draw spherical cap.It’s hard to me now.What I want to know is whether there is some function to draw spherical cap.It is better to add texture easily.
What do you think of it?I am anxious of you.
PS:my english is not good,please excuse me.
Well one way and a relatively easy way would be to use a Modeling package such as 3ds,Max, Multgen-Creator, Lightwave etc
Create your model in that, texture it in that and use or write a model loader to load into your Opengl Application etc…
OR convert that into opengl data… theres converters out there.
But I think he wants to do it using for loops and such thing, in runtime, right?..
- As a side question, Im loading an obj which has arround 4000 triangles, thing is… I get 10 fps or even lower, im doing many calls maybe? I call glVertex3f on every loop 3 times, and inside of them some procedures of mine which retrieves data from the structure (in where I stored the loaded data from the mesh file) … is there any better method? im not in c++ by the way
but I am not familiar with 3ds max,and I have to draw a primitive from a database.What can I do?
