[vtk-developers] Failed tests

Tue Jun 26 23:40:48 EDT 2018

With respect to the TestSpherePoints/TestSphereVertex tests the problem seems to be in vtkOpenGLPolyDataMapper::ReplaceShaderNormal() with the substituted text for the shader. When the following is commented out the points show as squares. Otherwise they are altogether absent.

  //if (this->DrawingSpheres(*this->LastBoundBO, actor))
  //{
  //  vtkShaderProgram::Substitute(FSSource,
  //    "//VTK::Normal::Dec",
  //    "uniform float ZCalcS;\n"
  //    "uniform float ZCalcR;\n"
  //    );
  //  vtkShaderProgram::Substitute(FSSource,
  //    "//VTK::Normal::Impl",

  //    " float xpos = 2.0*gl_PointCoord.x - 1.0;\n"
  //    " float ypos = 1.0 - 2.0*gl_PointCoord.y;\n"
  //    " float len2 = xpos*xpos+ ypos*ypos;\n"
  //    " if (len2 > 1.0) { discard; }\n"
  //    " vec3 normalVCVSOutput = normalize(\n"
  //    "   vec3(2.0*gl_PointCoord.x - 1.0, 1.0 - 2.0*gl_PointCoord.y, sqrt(1.0 - len2)));\n"

  //    " gl_FragDepth = gl_FragCoord.z + normalVCVSOutput.z*ZCalcS*ZCalcR;\n"
  //    " if (cameraParallel == 0) {\n"
  //    "  float ZCalcQ = (normalVCVSOutput.z*ZCalcR - 1.0);\n"
  //    "  gl_FragDepth = (ZCalcS - gl_FragCoord.z) / ZCalcQ + ZCalcS; }\n"
  //    );

  //   shaders[vtkShader::Fragment]->SetSource(FSSource);
  //   return;
  //}

One thing you might try is commenting out this line in vtkOpenGL2ContextDevice2D.cxx, it is around line 1169
    // We can actually use point sprites herecomment this ->    // if (this->RenderWindow->IsPointSpriteBugPresent())    {
Well that fixed the chart tests. Now there's just vtkRenderingOpenGL2Cxx (spheres and verticies) and vtkRenderingVolumneOpenGL2Cxx (depth peeling). I will investigate further.

I updated the graphics card drivers but it made no difference.

What I did find is that if I explicitly set the plot points marker style to either VTK_MARKER_CROSS or VTK_MARKER_SQUARE in the TestLinePlot2 test it works; although it always draws squares. 
VTK_MARKER_PLUS, VTK_MARKER_CIRCLE and VTK_MARKER_DIAMOND produce nothing. The default style is VTK_MARKER_CIRCLE

 In case no one has suggested this yet, have you made sure you have the latest driver? That seems to often solve these types of issues.

Hi.

I recently built and ran the VTK tests with VS2017 on a 64bit Windows 10 laptop with a Radeon graphics card.

With respect to vtkChartsCoreCxx and vtkRenderingOpenGL2Cxx the failures all exhibit the same feature - no points/verticies. I have attached images to illustrate the problem. I don't know if it is relevant, but I noticed an inability to display points in SalomE (which uses VTK for displaying meshes) many years ago after switching from a desktop machine with a Nvidia graphics card to a laptop with a Radeon graphics card. I always assumed the bug was in SalomE, but it might be this failure in VTK itself.
