Can be generated from real earth elevation data or procedurally and can be populated with vegetation.\n* Geo-referenced objects, with parent-child relationship\n* Q3D file format, with a python script to export from Blender\n* Scenes are setup in a XML file or at runtime\n* Basic animation classes\n\n## Things to code or to fix\n\n### Optimize\n* Frame rate drops too fast when scene goes up in complexity. Probably too much overhead on object/material setup.\n\n### Terrain\n* Tile seams : for now, seams between terrain tiles are visible. Should create small patches on edges to match tiles.\n* Z-fighting : should use an adaptive z-buffer depth to avoid this.\n* Loading : sometimes tiles simply don't show up.\n* Vegetation rendering : vegetation objects (and all alpha containing objects) should be rendered last to avoid alpha problems.\n* Vegetation spawning : still some bug in this algorithm.\n\n### Animation\n* Skinning : nothing done yet.\n\n### Camera\n* Frustum : sometimes objects disappear because they are not considered inside the viewing frustum (although we know they are).\n\n### Materials\n* PBR rendering : allow scripting of PBR methods for realistic shading.\n* Shaders: there are some artefacts due to bad looping when using perlin noise.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjango73%2Fquick3d","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjango73%2Fquick3d","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjango73%2Fquick3d/lists"}
