From 8cab401d08f8e25aa9b2dc710204785858ff3dbb Mon Sep 17 00:00:00 2001 From: Juan Linietsky Date: Mon, 15 Sep 2014 11:33:30 -0300 Subject: 3D Physics Rework, Other Stuff -=-=-=-=-=-=-=-=-=-=-=-=-=- 3D Physics: -Fixed "Bounce" parameter in 3D -Fixed bug affecting Area (sometims it would not detect properly) -Vehicle Body has seen heavy work -Added Query API for doing space queries in 3D. Needs some docs though. -Added JOINTS! Adapted Bullet Joints: and created easy gizmos for setting them up: -PinJoint -HingeJoint (with motor) -SliderJoint -ConeTwistJoint -Generic6DOFJoint -Added OBJECT PICKING! based on the new query API. Any physics object now (Area or Body) has the following signals and virtual functions: -input_event (mouse or multitouch input over the body) -mouse_enter (mouse entered the body area) -mouse_exit (mouse exited body area) For Area it needs to be activated manually, as it isn't by default (ray goes thru). Other: -Begun working on Windows 8 (RT) port. Compiles but does not work yet. -Added TheoraPlayer library for improved to-texture and portable video support. -Fixed a few bugs in the renderer, collada importer, collada exporter, etc. --- drivers/theoraplayer/src/YUV/yuv_util.c | 39 +++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 drivers/theoraplayer/src/YUV/yuv_util.c (limited to 'drivers/theoraplayer/src/YUV/yuv_util.c') diff --git a/drivers/theoraplayer/src/YUV/yuv_util.c b/drivers/theoraplayer/src/YUV/yuv_util.c new file mode 100644 index 0000000000..f5bf3e5f9e --- /dev/null +++ b/drivers/theoraplayer/src/YUV/yuv_util.c @@ -0,0 +1,39 @@ +/************************************************************************************ +This source file is part of the Theora Video Playback Library +For latest info, see http://libtheoraplayer.googlecode.com +************************************************************************************* +Copyright (c) 2008-2014 Kresimir Spes (kspes@cateia.com) +This program is free software; you can redistribute it and/or modify it under +the terms of the BSD license: http://opensource.org/licenses/BSD-3-Clause +*************************************************************************************/ +#include "yuv_util.h" + +struct TheoraPixelTransform* incOut(struct TheoraPixelTransform* t, int n) +{ + // used for XRGB, XBGR and similar + t->out += n; + return t; +} + +void _decodeAlpha(struct TheoraPixelTransform* t, int stride) +{ + int width = t->w; + unsigned char *ySrc, *yLineEnd, *out; + int luma; + unsigned int y; + for (y = 0; y < t->h; y++) + { + ySrc = t->y + y * t->yStride + width; + out = t->out + y * stride; + + for (yLineEnd = ySrc + width; ySrc != yLineEnd; ++ySrc, out += 4) + { + luma = (*ySrc); + // because in YCbCr specification, luma values are in the range of [16, 235] + // account for 'footroom' and 'headroom' ranges while using luma values as alpha channel + if (luma <= 16) *out = 0; + else if (luma >= 235) *out = 255; + else *out = (unsigned char) (((luma - 16) * 255) / 219); + } + } +} -- cgit v1.2.3
