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. 7042 1 sgothel 2024-01-20 05:22:18 +0100 commit 1040bed4ecc6f4598ea459f1073a9240583fc3c3 Add Cube to Frustum Plane mapping, supporting transformation of object-space AABBox into model-view Cube to Frustum.Plane for culling (cpu) and clipping (gpu) +++ commit 5cca51e32999a882e2a5f00cb45ecafc824ffd86 Frustum: Revise code and its Plane definition to support Cube->Frustum as well as to extract planes for float[] vec4-shader uniforms. commit 1040bed4ecc6f4598ea459f1073a9240583fc3c3 added AABBox -> Cube -> Frustum mapping (incomplete) and requires Frustum.Plane.set(..) by normal and point-on-plane for distance. Frustum.isOutside(Cube) has been added, testing all its 8-points similar to AABBox. Further all 6 Frustum.Plane shall be extracted to Vec4f and float[], the latter to pass the whole float[4*6] as a vec4[6] uniform array to the shader. Constructor, setter and getter have been adjusted accordingly. Most of the loops have been unrolled. Method names to query Frustum, i.e. 'is*Outside(<Type>)' have been reduced to 'isOutside(<Type>)' where <Type> uniquely indenticates the purpose. Hence only 'isSphereOutside()' is left over. +++ commit c1531c3d99b19032040018b9414263b0d3000147 Graph Clipping: Use Frustum Clipping using AABBox -> Mv transformed Cube -> 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} 7047 2 sgothel 2024-01-20 05:43:26 +0100 Screenshot w/ debug code demonstrating the Frustum clipping w/ rotation. The red-part is clipped by the shader, while the other thousand Glyphs of that glyph-grid are culled by the Group. https://jogamp.org/bugzilla//show_bug.cgi?id=805#c17 7048 3 sgothel 2024-01-20 05:44:08 +0100 (In reply to Sven Gothel from comment #2) (wrong link) https://jausoft.com/blog/wp-content/uploads/2024/01/FontView01-norm-q1-s01-fsaa4-FreeSerif_Regular_cp106-snap04-1280x0720-1.png
