可?#22253;碠CC文档上的说明,先更新显卡驱动试试。

Hello,

有可能是显卡支持的不好。
在Draw Test Harness中输入命令:
vglinfo
看看你的显卡信息。

On desktop, 3D viewer for optimal performance requires graphics processing unit (GPU) supporting OpenGL 3.3 or above. Ray tracing requires OpenGL 4.0+ or OpenGL 3.3+ with GL_ARB_texture_buffer_object_rgb32 extension. Textures within ray tracing will be available only when GL_ARB_bindless_texture extension is provided by driver.
On mobile platforms, OpenGL ES 2.0+ is required for 3D viewer (OpenGL ES 3.1+ is recommended). The ray tracing is not yet available on mobile platforms. Some old hardware might be unable to execute complex GLSL programs (e.g. with high number of light sources, clipping planes).
OCCT 3D Viewer, in general, supports wide range of graphics hardware - from very old to new. Therefore, if you observe some unexpected visual issues - first check for OpenGL driver update (or firmware update in case of mobile platforms); but beware that driver update might also come with new bugs. Don't forget to report these bugs to vendors.

re: OpenCASCADE 的安装与编译

博主您好,
我现在使用的是OCC7.2版本的,我试着编译打开MFC的案例,发现里面的贴图功能最后贴出来的图是黑色的(瓶子,地图,厨房被贴的地方都是黑色的),没有效果,不知道是什么原因?是我没配置好,还是OCC这方面功能还不完善?

re: PipeCAD之管道标准库PipeStd

@ccsdu2009
谢谢。

先做一版看看有没有效果。

有效果后面可以用Python之类的,方便扩展和分工。

re: PipeCAD之管道标准库PipeStd

good idea
不过单使用c++效率实在太低 建议考虑py或者js
