FreeGLUT | svn repo on sourceforge , for easy contribution | Game Engine library

I'm trying to get started in learning how to make graphics with C.

I and my college project partner are doing this project. We write this in c++ and OpenGL 2.1 with the freeglut.lib We turned the cylinder to lay down on the ground by 90 degrees. Now the cylinder is oddly misshaped. How can we fix the misshape? Is this a perspective thing? We wanted to use the cylinder later as wheels for a car which we should animate driving in a circle track. Right now the wheels on the car are only 2D circles.

I have a very simple example of a OpenGL ES program that I'm trying to get to run on RaspiOS Desktop (a.k.a. Raspbian) on Raspberry Pi 4.

My goal is very simple - to draw a red triangle in the center of the screen. However, the triangle comes out as white instead of red.

I've searched and tried everything and wasn't able to find any help. I'm very frustrated at this point because this was just supposed to be the first tutorial to introduce the world of OpenGL ES and I'm already stuck and can't continue with more complicated examples.

Anyway, here's the full example

I have the latest version of macOS Big Sur, running intel based cpu, clang12, cmake 3.19 and brew. I have installed freeglut via brew.

However whenever I called find_package(GLUT) it always finds my system GLUT (/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/GLUT.framework) over the FreeGLUT brew has installed. I have tried changing the find_package to FreeGlut with no success.

I am sure its something really simple I am missing but not knowing a lot about the macOS linking process, this has me rather confused.

Here is my cmake command line being used...

I am trying to use OpenGL with python. I have Pyton 3.7.4, on a Windows 10 machine.

I downloaded PyOpenGL and PyOpenGL_accelerate from .whl files, and I have downloaded the freeglut.dll file separately and placed it in the same directory as the script I am running.

My initial scripts is just:

I'm trying to get a QGLViewer application running on Windows, but the dependency management is madening. First of all, is there somewhere a comprehensible overview of the dependencies that are shared between a client application, Qt, QGLViewer, OpenGL, FreeGLUT/GLUT? What dependencies should be imported with CMake? What imports in c++ headers? Which dependencies are platform-dependent?

The error I get when compiling:

I didn't want to go back to the same question from yesterday, however before I am able to use the function to turn on and off the grid, I first need to know if my grid is actually working, I have been making new projects all night trying to display the grid but it isn't showing, the screen is always black and nothing is there at all.

I am trying to render a 2D square that has color and is transformed due to 4x4 matrices. The output is supposed to look like this:

However, I am instead getting this:

This is frustrating because I had this problem in another project. My professor walked me through how to solve it and all we did was play around with a few things here and there and it just magically worked, no code was altered. Now I am experiencing this issue again and there are no clues as to why this is happening. I typed the tutorial code correctly character for character and it is not being rendered correctly. It did however render correctly on my professor's computer.

Here is the code:

I am trying to create a car game with along with obstacles. I want to add collision so every time my object hits one of the obstacles, obstacle changes color and we know there has been a collision. I also want there to be a collision around my screen so that my object can not leave the view port?

--void 'draw car' is my movable object
