C++ (Cpp) QOpenGLFunctions::glDrawElements Examples

Example #1

File: shape_factory.cpp Project: HarryLong/CubeInSpace

void GlCircle::render()
{
    if(!initalised())
        initGL();

    m_vao_constraints.bind();

    QOpenGLFunctions * f = QOpenGLContext::currentContext()->functions();

    f->glDrawElements(GL_LINE_LOOP, m_indicies.size(), GL_UNSIGNED_INT, (void*)(0)); CE();

    m_vao_constraints.release(); // Unbind
}

Example #2

File: drawable_terrain.cpp Project: HarryLong/CubeInSpace

void DrawableTerrain::render()
{
    if(!initalised())
        initGL();

    QOpenGLFunctions * f = QOpenGLContext::currentContext()->functions();

    m_vao_constraints.bind();

    f->glDrawElements(GL_TRIANGLE_STRIP, m_indicies.size(), GL_UNSIGNED_INT, (void*)(0)); CE();

    m_vao_constraints.release();
}

Example #3
