- Fixed memory lead in Carve_getIntersectedOperandMeshes
- Union manifolds only if they intersects second operand, leave manifolds
which doesn't intersect second operand as-is.
Unioning of intersecting manifold tried to perform as little union operations
as possible, but there were some not totally correct assumption which lead to
cases when unioning of manifolds of some mesh might be happened when one of
mesh sets already had got intersecting manifolds.
This commit corrects this incorrect behavior.
Discovered this when was looking into #30175: Boolean Difference causes 2.62 RC1 crash.
Issue was caused by merging triangles into quads policy which used to think
triangulation of non-planar/non-concave quads happens by 1-3 diagonal which
isn't actually correct in some OpenGL implementations.
Added check for non-concave faces when merging triangles. It will work fine if
original faces are flat. In case if original faces aren't flat this check might
fail and triangulate face when it's not actually needed or merge triangles in
a way which leads to OpenGL artifacts.
very well for colors that can be outside of the 0.0..1.0 range, giving +/- infinity
results.
Now we just use a simple linear contrast factor as proposed by Paolo Sourvinos, and
clamp values to be >= 0, and also make the parameters work more in the 0..1 range
instead of the 0..100 range, to be more consistent with other nodes.
texture coordinates, due to int overflow.
Also minor tweak in shader code to avoid copying uninitialized
values, should have no effect though because they were not used.
We don't know how ALT key modifies the key, so utf=0;
That way Text Object can handle it.
* Should be removed when we able to support different keyboards on Windows
Issue was caused by union policy needed to deal with cases when operand intersects
two or more intersecting meshes of another operand.
Changed this policy to run union operation only if there's actual intersection
between two meshes of the same object. Should work in general but it's still
possible to make it behave incorrect -- for example object consist of two groups
if concentric cubes which intersects each other.
Currently supported passes:
* Combined, Z, Normal, Object Index, Material Index, Emission, Environment,
Diffuse/Glossy/Transmission x Direct/Indirect/Color
Not supported yet:
* UV, Vector, Mist
Only enabled for CPU devices at the moment, will do GPU tweaks tommorrow,
also for environment importance sampling.

Contrast helps to adjust IBL (HDR images used for background lighting).
Note: In the UI we are caling it Bright instead of Brightness. This copy what Blender composite is doing.
Note2: the algorithm we are using produces pure black when contrast is 100. I'm not a fan of that, but it's a division by zero. I would like to look at other algorithms (what gimp does for example). But that would be only after 2.62.
Issue was caused by left boolean operand consist of several intersecting manifolds
which make Carve triangulator confused and which can't be resolved in general case.
Added mesh pre-processing before actual applying boolean operator on it. This
preprocessing applies union operation on intersecting manifolds of the same object
so intersection edge loop with second object wouldn't confuse tesselator and correct
result would be returned.
Detecting of intersecting manifolds is based on AABB intersection check which leads
to some extra union operation called, but it's possible to speed things up from
Carve side so union operation of two not intersecting meshes would work faster.
Additional condition for running union for manifold is this manifolds intersects
AABB of second operand, so mesh topology wouldn't be changed at all in areas
where there's definitely no intersection between operands. It might be improved
so only manifolds which actually intersects second operand would be joined
together, but it'll slow things down a bit and prefer to do it only if it'll
be really a problem.
Additional change is fixed memory leak when boolean operation fails to run -
it was missed "delete" call if exception happens in Carve library.
From side effects of this change might be named boolean operation between
suzanne and another object: suzanne is consist of three intersecting open
manifolds, so this new meshes preprocessing leads to missed eyes in result
because of failure of merging two open manifolds. Don't think making suzanne
work for all setups should really be a goal, it's a bit crappy mesh for CSG
algorithms.
Description:
This patch allows the user to change the size of the window (or the resolution in fullscreen mode) using the new bge.render.setWindowSize() method. This only works in the Blenderplayer since it doesn't make a whole lot of sense for the embedded player.
By default lighting from the world is computed solely with indirect light
sampling. However for more complex environment maps this can be too noisy, as
sampling the BSDF may not easily find the highlights in the environment map
image. By enabling this option, the world background will be sampled as a lamp,
with lighter parts automatically given more samples.
Map Resolution specifies the size of the importance map (res x res). Before
rendering starts, an importance map is generated by "baking" a grayscale image
from the world shader. This will then be used to determine which parts of the
background are light and so should receive more samples than darker parts.
Higher resolutions will result in more accurate sampling but take more setup
time and memory.
Patch by Mike Farnsworth, thanks!
Tablet mode (stylus/eraser) wasn't properly set when pen was already hovering over
tablet surface when opening blender (i.e. in cases when blender was opened using
stylus tap).
Issue resolved by setting tablet mode when handling tablet's motion event too.
Error was caused by boost library (which doesn't seem to be working with Cycles too
when compiling with mingw). Switched mingw to use TR1 unordered collections. Also,
there was re-declaration of strcasecmp when mingw is used.
Additional changes are related on using own process spawning when BF_TOOLSET is set to
mingw. Seems to be working fine now (i've got too long command line error) and no
warning are supressing now (as it was told in comment for commented own process spawning).
