示例1: sun_azimuth
void
TerrainPreviewWindow::OnPaint(Canvas &canvas)
{
const GlueMapWindow *map = UIGlobals::GetMap();
if (map == nullptr)
return;
MapWindowProjection projection = map->VisibleProjection();
if (!projection.IsValid()) {
/* TODO: initialise projection to middle of map instead of bailing
out */
canvas.ClearWhite();
return;
}
projection.SetScreenSize(canvas.GetSize());
projection.SetScreenOrigin(canvas.GetWidth() / 2, canvas.GetHeight() / 2);
Angle sun_azimuth(Angle::Degrees(-45));
if (renderer.GetSettings().slope_shading == SlopeShading::SUN &&
CommonInterface::Calculated().sun_data_available)
sun_azimuth = CommonInterface::Calculated().sun_azimuth;
renderer.Generate(projection, sun_azimuth);
#ifdef ENABLE_OPENGL
/* enable clipping because the OpenGL terrain renderer uses a large
texture that exceeds the window dimensions */
GLCanvasScissor scissor(canvas);
#endif
renderer.Draw(canvas, projection);
