* Revert ".travis: sudo required for installing packages"Martin Stensgård2016-11-02
| | | | | | This reverts commit bbe3672be7584599b406a8349dd1efb8db8b6633. Because it might not have been needed after all.
* test-profile-arcs: march=core2Martin Stensgård2016-11-02
| | | | Maybe Travis will build it now.

|\ | | | | Make a headless entry point for benchmarking purposes
| * Add script to benchmark using -fprofile-useMorten Hustveit2015-11-05
| |
| * main_headless.c: Use multi-threadingMorten Hustveit2014-12-13
| |
| * Makefile.am: Use _LDADD for librariesMorten Hustveit2014-12-13
| |
| * Re-add center sphereMorten Hustveit2014-12-12
| |
| * Render to window dimensionsMorten Hustveit2014-12-12
| |
| * main_glut.c: Restrict raster position to inside of target windowMorten Hustveit2014-12-12
| |
| * ray.c: Allow self-reflections, now that we have concave objectsMorten Hustveit2014-12-02
| | | | | | | | Also update the animation a bit.
| * ray.c: Add specular color multiplier, and fix some shading bugsMorten Hustveit2014-12-02
| |
| * main_glut.c: Enable threading by defaultMorten Hustveit2014-12-02
| |
| * main_glut.c: Enable double bufferingMorten Hustveit2014-12-02
| | | | | | | | This prevents screen flickering during screen updates.
| * main_glut.c: Clear window and center animationMorten Hustveit2014-12-02
| |
| * Subtract the central sphere, and update the animation to matchMorten Hustveit2014-12-02
| |
| * ray.c: Prevent lights from subtracting color in the shadeMorten Hustveit2014-12-02
| | | | | | | | Also add some ambient light.
| * ray.c: Add missing freeMorten Hustveit2014-12-02
| |
| * ray.c: Halve the FOVMorten Hustveit2014-12-02
| | | | | | | | This makes the spheres look more spherical.
| * ray.c: Calculate lighting only for nearest hitMorten Hustveit2014-12-02
| | | | | | | | This loses 5ms/frame on yelena.
| * ray.c: Calculate reflection only once per hitMorten Hustveit2014-12-02
| | | | | | | | This saves 10ms on yelena.
| * main_headless.c: Remove whitespace at end of linesMorten Hustveit2014-12-02
| |
| * ray.c: Create only one thread per coreMorten Hustveit2014-12-02
| |
| * ray.c: Use __builtin_expect to mark sphere collisions as unlikelyMorten Hustveit2014-12-02
| | | | | | | | This saves 10ms/frame on yelena.
| * 3dmath.c: Remove sqrt from sphere_intersectMorten Hustveit2014-12-02
| | | | | | | | | | Interestingly, this seems to only save 1ms/frame on yelena. But that's still 16% of a 60fps frame.
| * ray.c: Don't look for self in reflection on selfMorten Hustveit2014-12-02
| |
| * ray.c: Simplify trace_lineMorten Hustveit2014-12-02
| | | | | | | | This doesn't save any time.
| * ray.c: Skip normalizing if light has negative contributionMorten Hustveit2014-12-02
| | | | | | | | This saves about 3ms/frame on yelena.
| * 3dmath.c: Early out of sphere_intersect on t <= 0Morten Hustveit2014-12-02
| | | | | | | | | | | | | | The loop in ray.c discards any data from intersections with t <= 0 anyway, so we might as well not calculate it. This saves 15 ms/frame on yelena.
| * 3dmath.c: Throw restrict on all parameters to sphere_intersectMorten Hustveit2014-12-02
| | | | | | | | This saves 3ms / frame on yelena.
| * 3dmath.c: In normalize, calculate reciprocal only once, and use sqrtfMorten Hustveit2014-12-02
| | | | | | | | This saves about 12ms per frame on yelena.
| * ray.c: Precalculate per-pixel ray directionsMorten Hustveit2014-12-02
| | | | | | | | This saves 16ms/frame on yelena.
| * 3dmath: Use const-correct function declarationsMorten Hustveit2014-12-02
