Hi Andreas,<div><br></div><div>For the total GPU memory, you can look at <a href="http://vtk.org/doc/nightly/html/classvtkGPUInfo.html">http://vtk.org/doc/nightly/html/classvtkGPUInfo.html</a><br><br></div><div>Regards,</div>

<div> </div>
<div>how can i get the maximum available texture memory? I am working on a volumerendering tool using vtkOpenGLGPUVolumeRayCastMapper. I have to deal with large volume data and want to figure out if the data fits in the texture memory in one block. My idea is to call <font size="1"></font></div>
<div><font face="times new roman, new york, times, serif"><font><font color="#030003"><font color="#030003"></font></font></font></font> </div>
<div><font face="times new roman, new york, times, serif"><font><font color="#030003"><font color="#030003">glTexImage3D</font></font>(<font color="#030003"><font color="#030003">GL_TEXTURE_3D</font></font>,0,<font color="#0000ff"><font color="#0000ff">static_cast</font></font><<font color="#030003"><font color="#030003">GLint</font></font>>(<font color="#030003"><font color="#030003">nInternalFormat</font></font></font>),</font></div>
<div><font><font face="times new roman, new york, times, serif"><font color="#030003"><font color="#030003">nExtent</font></font>[1] +1,<font color="#030003"><font color="#030003">nExtent</font></font>[3] +1, <font color="#030003"><font color="#030003">nExtent</font></font>[5] +1,0, <font color="#030003"><font color="#030003">nFormat</font></font>, <font color="#030003"><font color="#030003">nType</font></font>,0);</font></font></div>
<div><font></font> </div>
<div><font>at the beginning and see if i can reserve a block of a desired size. But if this function succeeded the mapper cant allocate such a big block anymore(without calling the function it works). I guess the glTexImage function reserves the block and i have to release it. But i dont know how and i need help! </font></div>
<div><font></font> </div>
<div><font>And is there a tool to tray the grafic cards memory? I would like to see how much texture and video memory is in use<var></var> and free in total.</font></div>
<div> </div>
<div>Thanks in advance</div>
