I'm trying to implement ImGui in my opengl app, but, for some reasons, the flag: ImGuiConfigFlags_DockingEnable is not found. I even tried to go in the files an
trying to implement shadow. I checked my depth texture on a quad, and it seems correct, but the shadow is not displaying. I check my shadow vertex and fragment
I'm attempting to render a .png image as a texture. However, all that is being rendered is a black square. Can anybody see any mistakes in my OpenGL GL_TEXTU
I am loading textures in using the following code: var texture = new SharpGL.SceneGraph.Assets.Texture(); texture.Create(gl, filename); But when I render them
I am getting the following error while compiling a simple imgui+glfw+opengl3 program on GCC 11.2.0 on Pop!_OS (Ubuntu): [build] In file included from ../externa
I want to use OpenGL without GLFW, the docs say that I need to add opengl32.lib to linker dependencies. How do I specifically import OpenGL an
In a typical building of a vertex-array-buffer, I am trying to pass an unsigned int attribute along side other classical ones (vertex, normal, texture coordinat
I've been developing a 2D Engine using SFML + ImGui. The editor is rendered using ImGui and the scene window is a sf::RenderTexture where I draw the GameObject
The texture gets generally worse more I move the camera away from the object. I need to be really close to the object for the texture to be fine. Does anyone kn

I'm trying to move the perspective view, so I can see that the sun, earth, and moon is moving around on a screen. I'm keep searching and trying to fix this but
I have seen instanced rendering using a vertex attribute buffer. So in addition to your usual data such as 'position' and 'normal' you have an extra 'attribute'
I am manually raytracing a 3D image. I have noticed that, the farther from the 3D image I am, the bigger the aliasing. This 3D image is basically a voxelized r
I'm trying to handle the transform of texture in fragment shader. the resolution of window is (640,360), the rotation is 30 degree, and the scale is vec2(0.5,0.
