From d39cdd8e1cfdcf9992f03f6ef72138dbdc3f6bbb Mon Sep 17 00:00:00 2001 From: Filippos Karapetis Date: Fri, 14 Oct 2011 13:51:59 +0300 Subject: SCI: More work on the vertical plane offset for SCI32. Still WIP. Vertical clipping is still not finished. This fixes the display in the Torin demo (which uses a scene with loads of items with a vertical offset). --- engines/sci/graphics/frameout.cpp | 36 ++++++++++++++++++++++++----- engines/sci/graphics/frameout.h | 1 + engines/sci/graphics/picture.cpp | 48 +++++++++++++++++++++++++++++---------- engines/sci/graphics/picture.h | 5 ++-- 4 files changed, 70 insertions(+), 20 deletions(-) (limited to 'engines/sci/graphics') diff --git a/engines/sci/graphics/frameout.cpp b/engines/sci/graphics/frameout.cpp index 9d15c8233f..9a44f07a60 100644 --- a/engines/sci/graphics/frameout.cpp +++ b/engines/sci/graphics/frameout.cpp @@ -90,6 +90,7 @@ void GfxFrameout::kernelAddPlane(reg_t object) { newPlane.priority = readSelectorValue(_segMan, object, SELECTOR(priority));
