set shader mode
by 刘先勇 14 Apr '13

Dear all, I set the color for each face of the bounding box. It looks right if I used "colored per-face, flat shaded". But I use "colored per-face, smooth shaded", the box turns to be a black one. What 's the matter? Please give me some ideas. Thanks. Regards, Xianyong Liu.

Fwd: Integrate libQGLViewer
by 刘先勇 14 Apr '13

Dear all, I was frustrated last night, because I failed to integrate libQGLViewer into OpenFlipper. It is just a very simple example. Any ideas? Or, If I want to show up a new window with glutCreateWindow("demo");, where I can draw primitives using OpenGL. How can I do that? Thanks. //**************** caller SimpleViewer simplerviewerHelpme; /*#if QT_VERSION < 0x040000 // Set the viewer as the application main widget. application.setMainWidget(&simplerviewer); #else simplerviewer.setWindowTitle("simpleViewer"); #endif*/ // Make the viewer window visible on screen. //simplerviewerHelpme. //*********************** #ifndef CS554PROJ2PLUGINSIMPLEVIWER_HH #define CS554PROJ2PLUGINSIMPLEVIWER_HH #include <QGLViewer/qglviewer.h> class SimpleViewer : public QGLViewer { protected : virtual void draw(); virtual void init(); virtual QString helpString() const; }; #endif //********************* #include "simpleViewer.h" using namespace std; // Draws a spiral void SimpleViewer::draw() { const float nbSteps = 200.0; glBegin(GL_QUAD_STRIP); for (int i=0; i<nbSteps; ++i) { const float ratio = i/nbSteps; const float angle = 21.0*ratio; const float c = cos(angle); const float s = sin(angle); const float r1 = 1.0 - 0.8f*ratio; const float r2 = 0.8f - 0.8f*ratio; const float alt = ratio - 0.5f; const float nor = 0.5f; const float up = sqrt(1.0-nor*nor); glColor3f(1.0-ratio, 0.2f , ratio); glNormal3f(nor*c, up, nor*s); glVertex3f(r1*c, alt, r1*s); glVertex3f(r2*c, alt+0.05f, r2*s); } glEnd(); } void SimpleViewer::init() { // Restore previous viewer state. restoreStateFromFile(); // Opens help window help(); } QString SimpleViewer::helpString() const { QString text("<h2>S i m p l e V i e w e r</h2>"); text += "Use the mouse to move the camera around the object.

SGP Software Award Solicitation
by Jan Möbius 05 Apr '13

05 Apr '13

Continuing with the tradition established two years ago, SGP and Geometry Factory will present the third software award at this year’s SGP, encouraging researchers to produce and share high-quality code. To this end, we would like to solicit nominations from the community for candidate code: awardnominations(a)geometryprocessing.org The goal of the award is to support researchers who go beyond the call-of-duty in making their code publicly available, thereby making it easier for our community to build on their research and helping advance our field. We are open to considering both code from within our field (e.g. geometry processing and computational geometry) and from without (e.g. numerical methods). While availability of source code is desirable as it makes it easier for researchers to explore new variations, we will also consider code released in executable and library/header-file format. In evaluating the code we will consider (among other factors): robustness of execution, quality of documentation, breadth of applicability, and ease of integration/extension. The deadline for nominations will be May 5th 2013. —The SGP Software Award Committee

How to change the visualization mode programmatically.
by 刘先勇 04 Apr '13

04 Apr '13

Dear OpenFlipper, I hope you are well. Could I propose a small question: Right click on a mesh, which was loaded onto the scene, we can manually change the visualization mode. I wonder how to realize it in code, no by physical manipulations. Best Regards, Xianyong Liu.
