i'd go for opengl..
1) it's open heh. so there are more ppl working on it than u think
2) it's been ported to more platforms then DirectX, and i can bet on that

I was in a discussion with one of my friend today, he said that openGL is getting outdated and obsolete, I should try to learn DirectX instead. Well, what's you guy's opinion? If I was to start graphics, what should I learn to program in? |

opengl in my opinion it is better than directx the only thing that may be obsolete about ogl (just for your info doom3 uses ogl) is the functional interface, which in my opinoin, doesnt matter much considering its an api ogl pros- cross platform, simple continuoes interface, powerful cons-no support libraries,extension mechanism, controlled by group dx pros-support lib (DX utilities), new features directly built-in,powerful cons-windows only, controlled only my microsoft |

I remember i read somewhere that opengl works faster on the old graphic cards but directx is more compatible with the new ones... but i still think it's a matter of personal choice and what u wanna use it for... here's a comparison table.... <table border=2 cellspacing=2 cellpading=2> <tr> <td>Feature</td> <td>OpenGL 1.2 Core</td> <td>Direct3D 7</td> <td>Direct3D 8</td> </tr> <tr> <td>Operating System Support</td> <td>Windows (9x, NT, 2000), MacOS, BeOS, *nix, others</td> <td>Windows (9x, 2000, CE) <a href="#Note12">[12]</a></td> <td>Windows (9x, 2000) <a href="#Note12">[12]</a></td> </tr> <tr> <td>API Definition Control</td> <td>OpenGL ARB</td> <td>Microsoft</td> <td>Microsoft</td> </tr> <tr> <td>API Specification</td> <td>OpenGL Specification <a href="#Note10">[10]</a></td> <td>SDK/DDK Documentation and DDK Reference</td> <td>SDK Documentation</td> </tr> <tr> <td>API Mechanism</td> <td>includes and libraries</td> <td>COM</td> <td>COM</td> </tr> <tr> <td>Software Emulation of Unaccelerated Features <a href="#Note4">[4]</a></td> <td>Yes</td> <td>No</td> <td>No <a href="#Note11">[11]</a></td> </tr> <tr> <td>Extension Mechanism <a href="#Note5">[5]</a></td> <td>Yes</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Source Implementation Available <a href="#Note6">[6]</a></td> <td>Yes</td> <td>Yes</td> <td>No</td> <tr> <td>Fixed-Function Vertex Blending</td> <td>No</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Programmable Vertex Blending</td> <td>No</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Parametric Curve Primitives</td> <td>Yes</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Parametric Surface Primitives</td> <td>Yes</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Hierarchical Display Lists</td> <td>Yes</td> <td>No <a href="#Note8">[8]</a></td> <td>No <a href="#Note8">[8]</a></td> </tr> <tr> <td>Two-sided Lighting</td> <td>Yes</td> <td>No <a href="#Note1">[1]</a></td> <td>No <a href="#Note1">[1]</a></td> </tr> <tr> <td>Point Size Rendering Attributes <a href="#Note9">[9]</a></td> <td>Yes</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Line Width Rendering Attributes <a href="#Note9">[9]</a></td> <td>Yes</td> <td>No</td> <td>No</td> </tr> <tr> <td>Programmable Pixel Shading</td> <td>No <a href="#Note14">[14]</a></td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Triadic Texture Blending Operations</td> <td>No</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Cube Environment Mapping</td> <td>No</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Volume Textures</td> <td>Yes</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Multitexture Cascade</td> <td>No <a href="#Note13">[13]</a></td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Texture Temporary Result Register</td> <td>No</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Mirror Texture Addressing</td> <td>No</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Texture "Wrapping"</td> <td>No</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Range-Based Fog</td> <td>No</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Bump Mapping</td> <td>No</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Modulate 2X Texture Blend</td> <td>No</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Modulate 4X Texture Blend</td> <td>No</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Add Signed Texture Blend</td> <td>No</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Hardware Independent Z Buffer Access</td> <td>Yes</td> <td>No <a href="#Note2">[2]</a></td> <td>No <a href="#Note2">[2]</a></td> </tr> <tr> <td>Full-Screen Antialiasing</td> <td>Yes</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Motion Blur</td> <td>Yes</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Depth of Field</td> <td>Yes</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Accumulation Buffers</td> <td>Yes</td> <td>No</td> <td>No <a href="#Note7">[7]</a></td> </tr> <tr> <td>Picking Support</td> <td>Yes</td> <td>No <a href="#Note3">[3]</a></td> <td>No <a href="#Note3">[3]</a></td> </tr> <tr> <td>Multiple Monitor Support</td> <td>No</td> <td>Yes</td> <td>Yes</td> </tr> <tr> <td>Stereo Rendering</td> <td>Yes</td> <td>Yes</td> <td>No</td> </tr> </table> |

cool, thanks for the help, I think I will try to program with OpenGL. Now my friend also mentioned another point, he said that since Direct3D will be alot easier to program in and easier to understand, he suggested that I should learn how to program in Direct3D 9 to start, and I haven't been able to find much information on that (maybe I'm just not looking hard enough?) so Direct3D 9, or OpenGL? |

you leave my ASCII art alone. I must fulfill my role in being Chinesy, and if I can't draw real art (cuz all oriental people should be able to draw, play piano, play badminton, etc, etc), then I must be able to draw cyber art. I wonder if I can get an art credit in ASCII........ |
