Here is my problem, when I load in textures I load them in as SRGB to convert them into linear space. When I was writing to the default frame buffer provided by the windowing system I enabled...

i am new to this linux framebuffer so do anybody guide me to draw the line-graph in framebuffer. And i have the code to draw graph in turbo c but now in linux. So please help me out. Thank You, Ra...

So, I want to write a virtual monitor driver for mac. This is something similar to what screen recycler app does. I've been reading so many resources about driver programming and kext in general an...

I'm developing a little gamedev library. One of the elements of this library is a Canvas (offscreen drawing area), which is implemented through an OpenGL framebuffer. So far, everything's been good...

Every time after I call glClear(GL_COLOR_BUFFER_BIT);, I get the OpenGL error "invalid framebuffer operation". The call seems to work just fine, and nothing seems wrong. I call glClear(GL_COLOR_BU...

Short Version of Problem I am trying to access the contents of a RenderTexture in Unity which I have been drawing with an own Material using Graphics.Blit. Graphics.Blit (null, renderTexture, mat...

Have anyone done this succesfully? It seems whatever index format I use in the stencil render buffer glCheckFramebufferStatus(...) returns GL_FRAMEBUFFER_UNSUPPORTED. I've succesfully bound both a ...

I'm doing heavy computation using the GPU, which involves a lot of render-to-texture operations. It's an iterative computation, so there's a lot of rendering to a texture, then rendering that textu...

I'm having problems to read out the frame buffer of a camera using python. The camera (Xenics) is connected via USB and there is a dll which ships with the camera. I access this dll using ctypes. T...

I have a small OpenGL application that has been developed using GLUT. What are my best options to render directly to a Linux framebuffer (fbdev) with OpenGL, without an X-Server? I understand that ...

I've known that framebuffer is the final destination of the rendering pipeline and swapchain contains many image. So what is the relation between those two things? Which one is the actual render ta...

I am working on storing and restoring my OpenGL ES based application's state. I have a function to save the GL_RENDERBUFFER to dump the data with the following code: glBindFramebuffer(GL_FRAMEBUF...

Is it possible to draw texture (if it is with correct width, height and pixel format) directly to frame buffer without using vertices and shaders in Vulkan?

I have little background on how these hardware actually works, but now I'm required to learn how to write a Linux frame buffer driver for Android devices. I'm confused by Linux graphics stack. Fr...

I haven't found a clear explanation on how the Android graphics system works, specifically, does it use a display server, is it based on DirectFB or X11, etc. From what I've managed to piece toget...

Does anyone knows how to draw an image in Linux, Raspberry Pi, Qt with double framebuffer in same time. I mean i want to run my application on LCD display and draw image to HDMI in same time.

A presentable image starts out in VK_IMAGE_LAYOUT_UNDEFINED but will be VK_IMAGE_LAYOUT_PRESENT_SRC_KHR after they have been presented once. A lot of examples do a transition of all vkImages to VK...

I'm learning about framebuffers right now and I just don't understand what the Color attachment does. I understand framebuffers. What is the point of the second parameter in: glFramebufferTexture...

My Android program must use glBlitFrameBuffer() function to copy FrameBuffer object. But glBlitFrameBuffer() function is only supported on OpenGL ES 3.0+ devices. I want to support OpenGL ES 2.0+ d...

I have a program with about 3 framebuffers of varying sizes. I initialise them at the start, give them the appropriate render target and change the viewport size for each one. I originally thought...

I've searched for couple hours for a solution to my problem. First of all. I have HD 7800 series amd GPU, newest drivers. I'm trying to create framebuffer class which has all the framebuffer func...

I have a problem with rendering to texture and offscreen framebuffer with OpenGLES on iPhone. (source: imagehost.org) (source: imagehost.org) First image shows mahjong tiles rendered to CAEAGL...

I have two 2D textures. The first, an MSAA texture, uses a target of GL_TEXTURE_2D_MULTISAMPLE. The second, non MSAA texture, uses a target of GL_TEXTURE_2D. According to OpenGL's spec on ARB_text...

I am trying to render to multiple textures as COLOR_ATTACHMENTs without success. All I get from displaying them is a black screen (with a red clear fill) meaning my texture is read but is 'empty'. ...
