Dear Jan,
Thank you for the reply.
When I set the color format as "PolyMesh::Color(0.0, 1.0, 0.0, 1.0)", the following error occurs: --> Assertion failed!, Program:..., File: ...\VectorT_inc.hh, Line: 97, Expression: DIM==4.
*Here are some details about my application;* *1)* I am working on quad mesh (not triangular mesh). *2)* The Openflipper version that I am using is "OpenFlipper v1.0RC7". *3)* Vertex coloring works well, here is the code; m_mesh->request_vertex_colors(); m_mesh->set_color(m_mesh->vertex_handle(0), PolyMesh::Color(0, 255, 0));
PluginFunctions::setDrawMode(ACG::SceneGraph::DrawModes::POINTS_COLORED); emit updatedObject(m_targetObject->id(), UPDATE_COLOR); *4)* Vertex coloring using the color format as "PolyMesh::Color(0.0, 1.0, 0.0, 1.0)" ends with the same error (Assertion failed!). *5)* Edge coloring using the below code does not generate any error, but there is nothing seen in the Openflipper view. It seems that it is successfully set to the "POINTS_COLORED" drawmode, there is no model. When I set any other drawmode, model appears. m_mesh->request_edge_colors(); m_mesh->set_color(m_mesh->edge_handle(0), PolyMesh::Color(0, 255, 0));
PluginFunctions::setDrawMode(ACG::SceneGraph::DrawModes::EDGES_COLORED); emit updatedObject(m_targetObject->id(), UPDATE_COLOR);
Best.

Dear Möbius,
I would like to ask about giving colors to the edges and visualizing them on the Openflipper visualization framework. Here is my code, but I cannot see the colored edges;
m_mesh->request_edge_colors(); m_mesh->set_color(m_mesh->edge_handle(0), PolyMesh::Color(0, 255, 0)); PluginFunctions::setDrawMode(ACG::SceneGraph::DrawModes::EDGES_COLORED); emit updatedObject(m_targetObject->id(), UPDATE_COLOR);
Hi,
can you try to set the color as: m_mesh->set_color(m_mesh->edge_handle(0), PolyMesh::Color(0.0, 1.0, 0.0, 1.0));
as the color format used in OpenFlipper is Vec4f. Did you check in the viewer, that the draw mode has actually changed to the one you set here?
Best, Jan
