As an open-source program it's easy to find third-party additions that add even more functionality to the program. This is a surprisingly versatile program that allows users to make graphics with a variety of programming languages. GlFramebufferParameteri(GL_FRAMEBUFFER_EXT,GL_FRAMEBUFFER_DEFAULT_WIDTH, w) OpenGL is a vector graphics program that creates images in 2D and 3D.
GlFramebufferParameteri (GL_FRAMEBUFFER_EXT,GL_FRAMEBUFFER_DEFAULT_HEIGHT, h) Ī sample using this works on 7xxx series but not on 5xxx series. GlFramebufferParameteri(GL_FRAMEBUFFER_EXT,GL_FRAM EBUFFER_DEFAULT_WIDTH, w)
GlBindFramebuffer(GL_FRAMEBUFFER_EXT,noat) Related altough no_attachments extension is not adversited new entry points are present so I played with it using default and seems a simple test works on 79xx but not on 58xx Other new like GL_MAX_COMPUTE_ATOMIC_COUNTERS seem to work. GlGetIntegerv parameter has an invalid enum '0x91be' (GL_INVALID_ENUM) *getting GL_MAX_COMPUTE_WORK_GROUP_COUNT and GL_MAX_COMPUTE_WORK_GROUP_SIZE I get using debug_output bug: *using sbo on non compute shaders (like fragment shaders seems no be not correct) Seems to compile so please fix to be able to use not only 32767 bytes of shared mem but full 32768 bytes. I verify this issue is on shared mem size usage as using something like Size (GL_MAX_COMPUTE_SHARED_MEMORY_SIZE: 32768). Isn't a issue so 32 should work as for this conf each of this two shared arrays is size 8192 (sizeof(double)*32*32) so total shared mem usage is 2*8192 and is equal to reported max Layout (local_size_x = 32, local_size_y = 32) in Layout (local_size_x = BLOCK_SIZE, local_size_y = BLOCK_SIZE) in ĭiminishing BLOCK_SIZE to less than 32 seems to work. *using a compute shader with following launch size and shared arrays usage:
*using atomicMax and atomicMin on shared variables hang the GLSL compiler others like atomicOr are OK!
(please note all the samples I use for testing this work correctly on Nvidia OGL 4.3 cards) I have been testing new OGL compute shader and storage buffer objects extension and found following bugs (13.4 on 7950):
