C++ (Cpp) View3DSettings Examples

Example #1

File: Triangles.cpp Project: peter1000/vpaint

void Triangles::draw3D(Time time, View3DSettings & viewSettings)
{
    double z = viewSettings.zFromT(time);

    // Drawing
    glBegin(GL_TRIANGLES);
    for(unsigned int i=0; i<triangles_.size(); ++i)
    {
        glVertex3d(viewSettings.xFromX2D(triangles_[i].a[0]), viewSettings.yFromY2D(triangles_[i].a[1]), z);
        glVertex3d(viewSettings.xFromX2D(triangles_[i].b[0]), viewSettings.yFromY2D(triangles_[i].b[1]), z);
        glVertex3d(viewSettings.xFromX2D(triangles_[i].c[0]), viewSettings.yFromY2D(triangles_[i].c[1]), z);
    }
    glEnd();
}

Example #2

File: InbetweenVertex.cpp Project: gitter-badger/vpaint

void InbetweenVertex::drawRaw3D(View3DSettings & viewSettings)
{
    double eps = 1e-5;

    int k = 5; // number of samples per frame
    double t1 = beforeTime().floatTime();

    int lineWidth = 3;
    glLineWidth(lineWidth);
    glBegin(GL_LINE_STRIP);
