<p>‎<span dir="auto"><span class="autocomment">Forward compatibility breaking</span></span></p> <p><b>新規ページ</b></p><div>= Blender 2.74: Cycles =<br /> <br /> Cycles improvements include: Ray/Triangle BVH building is now watertight, a new QBVH tree traversal structure, various optimizations especially great memory related ones, a new pointiness attribute for the Geometry node, controlling of an object's texture space by another, ...<br /> <br /> == BVH ==<br /> * Ray/Triangle intersection is now watertight. This is expected to address quite a reasonable amount of reports from the bug tracker, plus it might help reducing the noise in some scenes. ({{GitCommit|f770bc4757a2}}) <br /> <br /> * Implementation of a QBVH optimization structure for CPU with SSE2 support and above. GPU rendering, non-SSE and 32bit processors still using regular BVH. ({{GitCommit|03f28553ff07}})<br /> <br /> == Optimization ==<br /> * Optimize black world backgrounds ({{GitCommit|cd723967970e}})<br /> * Optimize vector math node without links to a single value node. ({{GitCommit|43421e9c5354}})<br /> * Reduce lag between shader tree modification and viewport render ({{GitCommit|2dfe5e3}})<br /> * Fallback to bottom-top tile order when rendering from the command line ({{GitCommit|bb08502}})<br /> * Optimize memory usage when creating mesh attributes ({{GitCommit|1862fbf}})<br /> * Reduce memory used by background light update ({{GitCommit|0f65250}})<br /> * Optimize memory usage during BVH construction by freeing memory used by intermediate BVH vectors earlier ({{GitCommit|3bc9ac1}})<br /> <br /> == Nodes ==<br /> [[File:Rl_pointiness.png|350px|thumb|right|Pointiness attribute in action.]]<br /> * Added attribute indicating how &quot;pointy&quot; the geometry surface is. Available via &quot;Pointiness&quot; output of the Geometry node. ({{GitCommit|227a940}})<br /> * Added support for texture mapping from another object ({{GitCommit|df07a25}}).<br /> * Image texture node now supports sphere and tube mapping. ({{GitCommit|12ccac6}}, {{GitCommit|dda3554}})<br /> * Cubic image texture interpolation is now available on CPU (previously only for OSL). {{GitCommit|3b9d455}}<br /> {{clr}}<br /> <br /> == Various ==<br /> * Cycles now uses clipping plane instead of clipping sphere ({{GitCommit|54fd3f3}}).<br /> * Added field-of-view options to the equirectangular panorama camera ({{GitCommit|4118c1b}}).<br /> * Ignore preprocessing time in ETA calculation ({{GitCommit|193871a}})<br /> * Use lower progressive update timeout for preview rendering, gives more instant material feedback ({{GitCommit|888d810}})<br /> <br /> == Forward compatibility breaking ==<br /> <br /> There was an old bug with Mapping Node in Cycles which gave totally different result than Blender Internal and GLSL/Material viewport shading. it was caused by the flipped euler order in Cycles.<br /> <br /> It is now fixed ({{GitCommit|a1ffb49}}), but if this node is used, opening newer files in older blender will give incorrect results.</div>
