1. 使用CUDA核函数生成图像数据 2. 将数据传递给OpenGL驱动程序并进行渲染 实现这个功能需要按如下四个步骤: Step1: 申明两个全局变量,保存指向同一个缓冲区的不同句柄,指向要在OpenGL和CUDA之间共享的数据; Step2: 选择运行应用程序的CUDA设备(cudaChooseDevice),告诉cuda运行时使用哪个设备来执行CUDA和OpenGL (cuda...

我正在尝试编写函数,将OpenGL纹理转换为PyTorch张量,然后返回到C++应用程序中。为了测试它是否有效,我在张量中添加了128,基本上使图像变亮,然后在四边形上渲染得到的纹理。它基本上是有效的,但我正在经历一种奇怪的行为,其中部分纹理不受影响。 是原始纹理, 是张量中每个元素加128后的纹理。注意,像1/4的图像不受...

这一章是讲CUDA与Opengl的交互,还好之前看过一些与opengl有关的内容,但在程序里并没有涉及多少Opengl的东西,还是直接先看效果吧。 Nvidia logo 上代码: #include"../common/book.h"#include"../common/cpu_bitmap.h"#include"cuda.h"#include"cuda_gl_interop.h"#define DIM 512PFNGLBINDBUFFERARBPROCglBin...
I am writting a moudule which does OpenGL off-screen renderring. (using GLAD+GLFW+CUDA OpenGL interop) When using one object of this module, renderring goes well. But if I create two objects of this module (for example, object 1 used to render small image, object 2 used to render larg...
Cuda OpenGL Interop 笔者学业不精,这部分基础不牢,如有问题请读者不吝纠正 CUDA提供了一套API,专门解决这样的问题,省去了看起来很愚蠢的将内存拷贝回Host紧接着原封不动又拷贝回Device。 注册OpenGL 缓冲区到 CUDA 图形资源 GLuintbufferObj;cudaGraphicsResource*resource;glGenBuffers(1,&bufferObj);glBindBuffer(...
CUDA_ERROR_INVALID_GRAPHICS_CONTEXT = 219 This indicates an error with OpenGL or DirectX context. CUDA_ERROR_NVLINK_UNCORRECTABLE = 220 This indicates that an uncorrectable NVLink error was detected during the execution. CUDA_ERROR_JIT_COMPILER_NOT_FOUND = 221 www.nvidia.com CUDA Driver API ...
every CUDA/OpenGL interoperability API function in the CUDA driver API segfaults. Here’s some example code exhibiting the issue (which works if I use a GLX-created opengl context): #defineEGL_EGLEXT_PROTOTYPES // for EGL extensions
