1. ## Antialiasing Problem

I have drawn a molecular structure. i show the bonds with cylinders and atoms with spheres. the problem is that when i perform antialiasing then some part of sphere is hide by the cylinder and cylinder comes on the top. so visualization is not looking good. can any one help me?
2. ## [.net] book for .net framework

plz suggest me any book about the .net framework which is simple and easily understandable.
3. ## Spline problem

i have two points p1 and p2. and i want 2 more points(control points) so that i can make spline curve. but i dont know how to calculate the control points.can any body tell me.
4. ## drawing cylinder

i want to draw a single cylinder with two different colors such that half of the cylinder with red color and half of the cylinder with blue color. can any body tell me how it is possible ???
5. ## OpenGL rotation

consider the example of a cube at center (0,0,0) when i rotate this cube it rotate about its center i.e (0,0,0) correct. but when i changed the center to (0,0,1) and rotate, it doesnot rotate about its center (0,0,1) but it rotate about (0,0,0). so what i want is that, the cube is any where on the screen it rotate about its center i mean when cube is at center(0,0,1) then it rotate at center(0,0,1) when cube is at center (2,3,4) then it rotate at center(2,3,4).i m using C# with OpenGL.
6. ## OpenGL Printing in OpenGL

i m using OpenGL with C#. i want to print the image generated by the program. can anybody tell me ?
7. ## how to improve performance

i m working on molecular modeling application. i have generate some views based on cylinders and spheres. i have drawn around 2000 atoms. i have used spheres for atoms and cylinders for bonds. but the problem is that the rendering is very slow and transfromation is also performing slow. tell me what should i do to improve the performance.
8. ## [.net] how to improve performance

i m working on C# with OpenGL. i have drawn some molecular views based on cylinders and spheres(3D objects). in fact i stored every atom as object. if 2000 atoms are there then 2000 objects are allocated space in memory with its member data types(like int, string etc). the problem is that when i render the image it is taking alot of time and transformation is also very slow. tell me is this a problem of memory or something else?
9. ## how to calculate the angle

can anybody tell me how to calculate the angle between two points (x1,y1,z1) and (x2,y2,z2) in 3D space.
10. ## OpenGL coordinate system

does OpenGL use cartesian coordinate system? or any other.
11. ## OpenGL how to draw ribbons and pipes & planks in OpenGL

i m working on the molecular visualization application. can any body tell me about any molecular graphics libaray that supports the ribbon and pipes & planks representation of molecules. or can any body tell me how these complex 3d images are drawn so that i can make it myself.
12. ## problem in rotating two objects separately by mose

i want to rotate two 3d objects separately with mouse by picking each of them individually. but when i pick any one of them and rotate then both the objects rotate. can any body tell me how it can be rotate by mouse separately.i want to do this on the single view port.
13. ## OpenGL problem in picking in OpenGL

i want to rotate two object separately on the same viewport in OpenGL. first i picked the object then i rotate it but when i rotate the picked object the unpicked object is also rotate. can any body tell me how to roate object separately.
14. ## OpenGL how to make canvas in C#(CsGL) by using OpenGL

Can any body tell me how to make canvas to display things in OpenGL with C#.i m using CsGL wrapper class.or tell me any alternate without using canvas.
15. ## urgently needed

I want to rotate objects by mouse in OpenGL with C#(CsGL). can any body help me.it is urgently needed.
