    Texture Clamp Confusion

    Is there a way to change the range of GL_CLAMP or easily edit the U/V Coordinates? In an OBJ renderer that I am working on, texture clamping seems to be putting up a fuss.

    Texture Mapping Problem

    The texture is mapping oddly to the cube in OpenGL, but it looks just fine in the OBJ format. The U/V Coordinates are identical, I think. Do U/V Coordinates have to be formatted a little differently...

    I suppose not everyone is interested in compiling the source code for themselves. The left one is with glFrustum. The right one is with glOrtho. They are the same scene.

    Yet another topic about glFrustum.

    The glFrustum(); function is putting up a fight. I need to zoom in on the map and using glOrtho was causing it to disappear by the time any real distance was made, so someone suggested I use...

    Thank you for your response! I was using glFrustum(-320,320,-(WHEIGHT/2),WHEIGHT/2,-1000,1000);, but nothing was rendering. Using the glGetError() function resulted in an "Invalid Value" error which...

    Translation towards the camera.

    I probably already have a solution to the math behind moving the scene towards the camera, but it stops rendering when translated much at all and never seems to get closer to the camera even when it...

    Thanks! It is now a little closer! Some of the rotations are correct while others are wrong. Do you think it may have something to do with axis ordering?

    Camera magic?

    I understand that there isn't really a such thing as moving a camera around in OpenGL. Still, something odd is happening. I'll provide three chunks of code.

    Dynamic colors in OpenGL?

    glColor3f(1,0,0);

    I know that this is red, represented as 255. If I want to use 0x7F 0x0 0x0 for the colors, I would just need to divide each by 0xFF and get their decimal values and put those.

    Problem solved. :cool: For anyone with the same question as me in the future, just scale with a negative value.

    Mirror a model completely?

    I'm not looking for any fancy mirroring effects like a puddle. I just need a means of mirroring (flipping) a model along an axis.
