I have a 2D texture array of 8 layers attached to 8 color attachments of an FBO as so:...

I've been working on this hobby game engine in C and Sokol with CGLM for a short while now, and I've ran into a bit of a snag regarding portal rendering. It works as it should when the player camera's ...

As a way to estimate screenspace density of a set of particles, I'm trying to do some splatting: render a circle of fixed radius around each particle, accumulating, to get a count of how many ...

If we take screenshot of image displayed on a monitor screen, then does it take only framebuffer data? Does the framebuffer data is independent of display screen properties like contrast, brightness? ...

I want to implement shadows in my already existing glmatrix-based project.You can see my project's github source. It is classic scebe object based structure. I have draw functions, I render recalls....

I have written a relatively simple interactive C program using OpenGL 4.4 with a vertex shader and a fragment shader, running in the CodeBlocks IDE on Windows. I included an FPS counter basically as ...

Currently I have a basic (OpenGL 3.3) rendering scheme using a simple depth vertex shader to generate shadow maps for a scene. I don't care about having a large number of lights in the scene so it is ...

I have a scenario with several cameras. Each hold its own color and depth texture.Because the geometry of the environment is expansively procedural generated, I would like to combine cameras with ...

Is it proportional to the samples count?Whats the performance difference between binding a multi-sampler and a regular sampler?

The setupI have a working bloom shader implemented which creates a fbo with two textures attached to it.The first texture holds the entire sceneThe other only displays objects which are supposed ...

I'm just starting to work with framebuffer objects and am having trouble trying to figure out why I can't blit my framebuffer to my viewport. I know my framebuffer has data drawn to it since I can ...

I want to do some complicated stuff but have problems with my geometry shader / FBO bindings.To hold it as easy as possible I reduced the code to a minimum. If this works, I could continue the hard ...

I am trying to put multiple depthbuffers into one Framebuffer.I want to use VR and render both eyes at the same time:that means, in the geometry stage I want to clone the incoming triangle to two ...

My understanding is:the 'framebuffer' in OpenGL is a collection of buffers: many (due to swapping or stereo rendering) color buffers, (only one?) z-buffer and (only one?) stencil buffer;each OpenGL ...

I'm planning to write a small software rendering engine (before anyone asks, it's kind of a learning/scientific experiment for me).Before writing any code, I'm already stuck at the very first step: ...
