C++ (Cpp) DeleteShaderObject Examples

Example #1

File: mythrender_opengl2.cpp Project: mdda/mythtv

uint MythRenderOpenGL2::CreateShaderObject(const QString &vertex,
                                          const QString &fragment)
{
    if (!(m_exts_supported & kGLSL))
        return 0;

    OpenGLLocker locker(this);

    uint result = 0;
    QString vert_shader = vertex.isEmpty() ? kDefaultVertexShader : vertex;
    QString frag_shader = fragment.isEmpty() ? kDefaultFragmentShader: fragment;
    vert_shader.detach();
    frag_shader.detach();

    OptimiseShaderSource(vert_shader);
    OptimiseShaderSource(frag_shader);

    result = m_glCreateProgram();
    if (!result)
        return 0;

    MythGLShaderObject object(CreateShader(GL_VERTEX_SHADER, vert_shader),
                              CreateShader(GL_FRAGMENT_SHADER, frag_shader));
    m_shader_objects.insert(result, object);

    if (!ValidateShaderObject(result))
    {
        DeleteShaderObject(result);
        return 0;
    }

    return result;
}

Example #2

File: mythrender_opengl2.cpp Project: mdda/mythtv

void MythRenderOpenGL2::DeleteDefaultShaders(void)
{
    for (int i = 0; i < kShaderCount; i++)
    {
        DeleteShaderObject(m_shaders[i]);
        m_shaders[i] = 0;
    }
}

{
    DeleteShaderObject(shader);
    CTX_ANALYZER_FUNC1(DeleteShader, GLOutput, GL_OUT_BUF_SIZE, shader);
