* Graph Clipping: Use Frustum Clipping using AABBox -> Mv transformed Cube -> ↵Sven Göthel2024-01-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Frustum mapping + GraphUI Support AABBox clipping naturally couldn't be transformed into 3D Model-View (Mv) Space, as it is axis aligned and only provided 2 points (min/max). Therefor we map the Group's AABBox to a 8-point Cube, perform the Mv-transformation and then produce the 6-plane Frustum. As before, we cull fully outside shapes within the Group's draw method and perform fragment clipping with same Frustum planes in the shader. With clipping enabled, the 3D z-axis getBounds() depth will be slightly increased for functional Frustum operation. This is also done for setFixedSize(Vec2f). The Frustum planes are copied to the Graph shader via float[4*6] -> uniform vec4 gcu_ClipFrustum[6]; // L, R, B, T, N, F each {n.x, n.y, n.z, d} +++ Concludes related work of below commits - 1040bed4ecc6f4598ea459f1073a9240583fc3c3 - 5cca51e32999a882e2a5f00cb45ecafc824ffd86
* Graph/GraphUI: Revise Graph Region ShaderMapping, fix AABBox-Clipping for ↵Sven Göthel2024-01-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass2-AA, revise Pass2 AA Quality parameter .. Misc: - Graph VBORegion2PVBAAES2: Drop unused FBO rescale - Move MIN/MAX QUALITY/SAMPLE from GraphUI Scene -> Graph Region +++ Quality -> Pass2 AA Quality - Drop quality field in region - Pass quality to GLRegion.draw(..) similar to sampleCount for dynamic shader and switch - TODO: Pass quality parameter in TextRegionUtil's functions Fix RegionRenderer Shader Mapping - Use ShaderKey class to properly implement the hash value and equals method - For this, TextureSequence.getTextureFragmentShaderHashID() has been added to provide actual shader-snippet for the equals function - All required criterias are included in the hash value and equals method Fix AABBox Clipping for Pass-2 AA - Clipping in pass2-AA must happen in pass2 on actual gcu_PMVMatrix01 (not ortho) +++ GraphUI GraphShape - Rename: [get,set]{->AA}Quality() GraphUI Scene - Rename: mark{All->}ShapesDirty(), set{AllShapes->}Sharpness(), set{AllShapes->AA}Quality() - Fix setSampleCount(..), i.e. markStatesDirty() not markShapesDirty() - Fix setAAQuality(), markShapesDirty() and markStatesDirty(): Use forAll(..) to traverse through all shapes and groups. GraphUI Group - Add setFixedSize() - Add setClipOnBox() - Document setRelayoutOnDirtyShapes(), isShapeDirty()
* Graph Clipping: Add missing Modelview-Matrix (Mv) Multiplication / ConsiderationSven Göthel2024-01-091-1/+1
| | | | | | - GLSL vertex shader sets smooth varying 'gcv_ClipBBoxCoord' w/ Mv multiplied vertex-coord - RegionRenderer.setClipBBox(AABBox) expects a pre-multiplied Mv AABBox covering an independent area, not per Shape/Region. - This works as expected with moving/scaling of each Shape/Region etc
* Graph Clipping: GLSL: Add `USE_AABBOX_CLIPPING`, i.e. clipping via AABBox ↵Sven Göthel2024-01-091-4/+6
| | | | | | | | | | | | | | | min/max vec3 as convenient using Graph/GraphUI produced AABBox USE_AABBOX_CLIPPING - Conditional compilation w/ macro 'USE_AABBOX_CLIPPING' - gcv_ClipBBoxCoord smooth varying setup in vertex shader - fragment shader clips via branch if( is_inside(gcv_ClipBBoxCoord, gcu_ClipBBox[0], gcu_ClipBBox[1]) < 0.5 ) { CLIP } - clipping via discard or alpha=0 in case of buggy-discard. Other optimization: - Drop gcv_ColorTexExt, fragment-shader uses gcu_ColorTexBBox[2] directly (flat) - Simplified gcv_ColorTexCoord smooth varying equation in vertex shader.

* Bug 801: Cleanup shader-program location/data update ; Add COLORTEXTURE + ↵Sven Gothel2014-04-041-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TextureSequence to Region (Demo: TextureButton) Cleanup shader-program location/data update - GLUniformData: - Allow lazy data setup, as used for RenderState.ProgramLocal, see below - RenderState - Separate data (pmv, weight, colorStatic) from program-local uniforms -> add class ProgramLocal. Reduces uniform location lookups, since ProgramLocal is bound to Region impl. - ProgramLocal.update(..) needs to write uniform data always, since data is being used in multiple programs! - No 'dirty' tracking possible, removed - see above. - RegionRenderer - Fix shader-selection: 2-pass programs differ from 1-pass! - No shader-setup at init +++ Add COLORTEXTURE + TextureSequence to Region - Create color-texture coords in vertex-shader via region's bounding box (pass-1) - Use color-texture unit in pass-1 if enabled (own shader program) - Use TextureSequence in Region impl. providing all required data (unit + texture-name) - Demo: TextureButton (a UIShape)
* Bug 801: WIP 1/2 - Add color attribute; Switch Shader instead of branching ↵Sven Gothel2014-04-011-0/+30
in shader; Update attributes and uniforms manually, drop ShaderState; - ShaderCode - add int insertShaderSource(int shaderIdx, int position, Class<?> context, String path) - insertShaderSource(..): pos==-1 -> append code - VectorUtil - add isVec3InTriangle3(..., float epsilon) - add testSeg2SegIntersection(..., float epsilon) - add testTri2SegIntersection(..., float epsilon) - AffineTransform: Return result for chaining - Font - Add pixel precise 'getPointsBounds(final AffineTransform transform, CharSequence string, float pixelSize)' - Rename getString*() -> getMetric*() - OTGlyph: Release _points field, no more used - - Graph Triangulation - Count additional vertices in: Triangulator, CDTriangulator2D - OutlineShape: - Allow skipping of 'transformOutlines2Quadratic', i.e. allow tagging OutlineShape to be quadratic_nurbs via 'setIsQuadraticNurbs()' - Clarify cleanup ot outlines in same method 'cleanupOutlines()' - Count additional vertices .. - Graph Shader: - Start splitting and segmenting shader code for: - pass1 / pass2 - features, i.e. sampleCont, color-channel, ..
