* Graph Clipping: Use Frustum Clipping using AABBox -> Mv transformed Cube -> ↵Sven Göthel2024-01-202-27/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Frustum: Revise code and its Plane definition to support Cube->Frustum as ↵Sven Göthel2024-01-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Graph/GraphUI AA-Quality + SampleCount (shader): Push params down to ↵Sven Göthel2024-01-165-52/+89
| | | | | | | | | | | | | | | | | | RegionRenderer's RenderState usually rarely set from top of user API, reducing complexity. Discussion: Alternative was to pass AA-Quality same as SampleCount from the top (e.g. GraphUI Scene), however, this convolutes the API even more. Both parameter modify the resulting shader code in pass2 rendering (only). The used 'renderMode' is still maintained within the Region, since it contains more dynamic states individual to each Region instance (color-texture, ..). This despite 'renderMode' also changes the RenderState's shader program. In the end, it really doesn't matter and is a choice of frequency - the pipeline is usually rendering from on OpenGL rendering thread sequentially. AA-Quality and SampleCount simply usually don't change that often and are set only once.

* Graph Clipping: Add missing Modelview-Matrix (Mv) Multiplication / ConsiderationSven Göthel2024-01-092-0/+5
| | | | | | - 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | aspect-ratio, letter-boxed or zoomed (config) + Bug 1466 Fix color mixing Bug 1465: Region currently simply bloats a given texture to its region AABBox, which renders textures with the wrong aspect ratio. Add facility to program the texture-coordinates to either letter-box or scaled-up (and cut) true aspect-ratio. Default shall be zoom (scale-up and cut), but user shall be able to set a flag in the Region for letter-box. Have the shader clip texture coordinates properly, best w/o branching to soothe performance. See functions.glsl +++ Bug 1466: Current color mix: texture * color_channel * color_static is useless in GraphUI. color_static shall modulate the texture, which works. But in case of color_channel (attribute/varying) we want it to be mixed so it can become the more dominant color for e.g. a border. Desired is: color = vec4( mix( tex.rgb * gcu_ColorStatic.rgb, gcv_Color.rgb, gcv_Color.a ), mix( tex.a * gcu_ColorStatic.a, 1, gcv_Color.a) );

* Bug 1452 - Decouple math functionality to 'com.jogamp.math' to be toolkit ↵Sven Gothel2023-09-207-53/+50
| | | | | | | | | | | | | | | | | | | | agnostic (PMVMatrix, Matrix4f, Vec4f, ..) Math functionality (PMVMatrix, Matrix4f, Vec4f, ..) - shall be used toolkit agnostic, e.g. independent from OpenGL - shall be reused within our upcoming Vulkan implementation - may also move outside of JOGL, i.e. GlueGen or within its own package to be reused for other purposed. The 'com.jogamp.opengl.util.PMVMatrix' currently also used to feed in GLUniformData via the toolkit agnostic SyncAction and SyncBuffer shall also be split to a toolkit agnostic variant. An OpenGL PMVMatrix specialization implementing GLMatrixFunc can still exist, being derived from the toolkit agnostic base implementation. +++ Initial commit .. compile clean, passing most unit tests.

* Graph TextRegionUtil.drawString3D(..): Redefine 'rgbaColor' semantics: ↵Sven Gothel2023-08-021-3/+24
| | | | | | | | | | Either fill color-channel with value if used and set static-color to white - or just set static color channel with value. Have the given rgbaColor to definitely setting the text color regardless whether a color channel is used or not. Note: Using a color-channel is more expensive (color value per vertex) and should only be required if mixing colors within one region! Also removes potential side-effects if color-channel is used but user forgets to set the static value properly.
* Graph RenderState: Initialize colorStatic w/ all white (1,1,1,1) if ↵Sven Gothel2023-08-021-1/+1
| | | | | | | | | | | | color-channel is used and no static-color set Commit a973324a75b55b722caa755a7a573be849d997e4 was setting the alpha to 1, which avoids the 'discard' in the shader. This at least gave us a black color ;-) However, the shader modulates the color, i.e. color-channel * color-static, therefor we need an all-white color-static as default if user only sets the color-channel.
