Hi,<br><br>Currently using vtk-5.8.<br><br>While debugging my application, I noticed that the vtkOpenGLTexture::Load function always resets the this->SupportsPBO flag to "false" even though PBO's are supported by the platform. It seems to be caused by the ReleaseGraphicsResources function which resets everything _after_ we have checked the hardware support.<br>
<br>I did a quick test and commented the ReleaseGraphicsResources call from the Load function and now the PBO is correctly used. <br><br>So my question is:<br><br>Is this behavior caused by my application? I'm doing a lot of texture streaming and often update the vtkImageData object that is set as the input of the texture.<br>
<br>Regards, <br><br>Marc<br>
