Scaling a texture with a Framebuffer

My goal is to be able to scale textures when they are loaded, so I don\'t have to do it on every frame the sprite gets rendered. I figured the best method would be to render the scaled texture onto an[详细]

Is it possible to attach the default renderbuffer to a FBO?

I\'m considering refactoring a large part of my rendering code and one question popped to mind: Is it possible to render to both the screen and to a texture using multiple color attachments in a Frame[详细]

Example for rendering with Cg to a offscreen frame buffer object

I would like to see an example of rendering with nVidia Cg to an offscreen frame buffer object. T开发者_开发问答he computers I have access to have graphic cards but no monitors (or X server). So I wa[详细]

How can I successfully perform hidden line removal after pass through FBO?

I\'m trying to perform hidden line removal using polygon offset fill. The code works perfectly if I render directly to the window buffer but fails to draw the lines when passed through a FBO as shown[详细]

How do VBOs/FBOs/DisplayLists work in Haskell's OpenGl bindings?

Haskell is about computation by calculation of values. DisplayLists / FBOs / VBOs are very very stateful by nature. I.e. \"give me a display list /开发者_运维问答 buffer object\".[详细]

What is the best way to handle FBOs in OpenGL?

I wonder since a long time what would be the best way to handle OpenGL FrameBuffer Objects (FBO). Switching FBOs can be costly but defining new attachments too.[详细]

OpenGL frame buffer slow and spontaneously stalls. Can even cause a system crash when used extensively

Apparently frame buffers are fast and the best way to render offscreen to textures or to simply pre-create things.[详细]

Problem using FBO: Only first pass renders. A possible problem at setting render target back?

I have a huge problem with using FBO. I have a multi-pass display using FBOs and multitexturing. Everything seems to work fine until the end of first execution of display.[详细]
