* Have Renderable manage all instance lightsDan Goodliffe2026-04-01
| | | | | | Spot and point lights now existing in Renderable, the vertex data contains the owning parent object's index in CommonLocationData, the render step is just a single draw call.
* Fix VertexArrayConfigurator with derived classesDan Goodliffe2026-04-01
| | | | | | Fixing passing a pointer to member of base class; previously the offset was deduced relative to the structure it was in, not the vertex as a whole.
* Move light vertex structs outDan Goodliffe2026-03-31
|
* Use a single buffer for the location/rotation data of all renderable objectsDan Goodliffe2026-03-31
| | | | | | Removes the BufferedLocation and BufferedLocationUpdater mess. Note: appears to break bogie rendering in asset factory test only, same symptom as broken network render test? (out of date buffer data)
* Use uint32_t for indexes in InstanceVerticesDan Goodliffe2026-03-30
| | | | Passable to GLSL and more than big enough
* glAllocator revampDan Goodliffe2026-03-15
| | | | | | | Remove the map of buffers, now a fat pointer containing the buffer's name. This is accessible via the container's begin/end iterator. Move the bulk of the logic out of the template, it's mostly void * from the mapping anyway. Add allocate_at_least support.
* Add missing algorithm includeDan Goodliffe2026-03-15
|
* Avoid UB in calculating member offsetDan Goodliffe2026-03-15
| | | | Bit hacky; local dummy var to base a fake pointer on.
* Shared VAO for all 3 parts of RailVehicleClassDan Goodliffe2026-03-12
| | | | | | Rearranges its LocationVertex to be 3 repeated Parts. Adds helpers to glvglVertexArray for useBuffer with various offsets. Render is then an iteration of the meshes and the location data at the nth offset.
* Add missing typename exporting base::value_type from InstanceVerticesDan Goodliffe2026-03-11
|
* Sprinkling of glDebugScope in assets and render partsDan Goodliffe2026-03-11
|
* Split addAttribsFor away from requiring a buffer to bindDan Goodliffe2026-03-11
|
* Replace hacky m4 shader preprocessing with proper glslang versionDan Goodliffe2026-03-10
|
* Switch frame and render buffer to DSA helpersDan Goodliffe2026-03-10
|
* Switch to floating point, camera relative position bufferDan Goodliffe2026-03-10
|
* Specialise glTexture::savePositionDan Goodliffe2026-03-09
| | | | | Normalises the range of position information into the range 0-255 so the resulting image is remotely useful.
* Remove identifier naming lint comments, gl* is fineDan Goodliffe2026-03-08
|
* Move all low level texture operations to DSA helpers in glTextureDan Goodliffe2026-03-08
|
* Replace gl_traits glTexParameter with glTexture::parameter DSA wrapperDan Goodliffe2026-03-07
|
* Fix naming violations in MeshDan Goodliffe2026-03-07
| | | | | They've existed and been annoying since the day I first created it from online examples.
* Add glVertexArray useBufferDan Goodliffe2026-03-07
| | | | | | Wraps glVertexArrayVertexBuffer automatically getting the buffer name from the argument and deriving the stride from the container's value_type.
* Don't create and then replace shadow and billboard texturesDan Goodliffe2026-03-07
|
* Replace glContainer with glAllocatorDan Goodliffe2026-03-07
| | | | | | | glContainer is no longer required, as we can use std::vector with a custom allocator which uses OpenGL buffers for storage. Minor irritation is that the mapped buffers aren't guaranteed to be flushed in the tests, so sometimes we're missing bits in a test render.
* Remove VertexArrayObject and supporting non-DSA gl_traits helpersDan Goodliffe2026-03-06
|
* Replace use of VertexArrayObject with glVertexArray/glBuffer DSA versionsDan Goodliffe2026-03-06
|
* Extend glVertexArray with VertexArrayConfiguratorDan Goodliffe2026-03-06
| | | | DSA version of VertexArrayObject.
* Replace generic glBuffer type alias with a full implementationDan Goodliffe2026-03-06
| | | | Adds wrappers for DSA storage and data uploads.
* Replace basic glVertexArray with a specific class ready for helpersDan Goodliffe2026-03-04
|
* Update stencils and billboards less oftenDan Goodliffe2026-03-04
| | | | | | | No need to update these every frame when little of nothing has changed. Instead, track the angle previously rendered and updated only when the new angle has diverged sufficiently from this. Larger updates update more frequently.
* Wrap up some low level texture operations in glTexture classDan Goodliffe2026-03-02
| | | | Fixes previously hard coded billboard texture size.
* Add BillboardProgram to SceneShaderDan Goodliffe2026-02-28
| | | | | The implementation is overly simple/incomplete, I'm not even convince what is there is right, but it's a decent start.
* Allow specifying all three partition functions independentlyDan Goodliffe2026-02-28
| | | | | Two predicate version behaviour is unchanged, the second predicate is just the inverse of the third.
* Support for the BillboardPainterDan Goodliffe2026-02-28
| | | | | Based on the ShadowStenciller, creates flattened images of a model for simplified mass use in a scene.
* Tidy the preFrame logic into a single function in SceneRendererDan Goodliffe2026-02-23
| | | | | Clients now just call that one helper and SceneProvider passes in all the renderables.
* Reduce shader includes, doesn't use materialInterface, just DetailDan Goodliffe2026-02-20
|
* Simplified and tidied ShadowMapperDan Goodliffe2026-02-20
| | | | | No arbitrary 10m extra extents. No runtime vectors. Simpler code. Consts. etc.
* Fix up the preFrame process to use both frustumsDan Goodliffe2026-02-18
| | | | | | (camera and directional light frustums) This has made the whole preFrame process far more fiddly and repetitive than I'd like, but it does work. Maybe we can tidy it up later.
* Refactor test-instancing so the data is generated in a common fixtureDan Goodliffe2026-02-14
| | | | Includes exposure of InstanceVertices::reserve because why not.
* Add support for partitioning by 2 unary predicatesDan Goodliffe2026-02-14
| | | | | Second predicate creates a single block of truthy values in the middle, and two falsy blocks at each end.
* Return indices instead of iterates from InstanceVertices::partitionDan Goodliffe2026-02-14
| | | | More useful in the context of passing them to OpenGL.
* Make similar array tidy-up to networkStraight shadersDan Goodliffe2026-01-31
| | | | And merge common functionality from networkCurve.
* Tidy networkCurve shadersDan Goodliffe2026-01-31
| | | | | | | | | Arrays for start/end position/angle, smaller centre position, dynamic segment count based on max error, calculate distance in tessellation evaluation, use start/end position directly to avoid rounding errors at joins. See https://schneide.blog/2025/05/21/calculating-the-number-of-segments-for-accurate-circle-rendering/
* Rename shader source in keeping with glsl expectationsDan Goodliffe2026-01-31
| | | | | Swaps name/type of generated files to match class names and source files.
* Initial commit using tesselation shader to create curvesDan Goodliffe2026-01-31
| | | | Disables glslangValidator because of file extension mess up.
* Update OpenGL context and shaders to v4.6Dan Goodliffe2026-01-29
| | | | | Note: doesn't remove/replace older functions where newer ones might be better.
* Fix search/replace of GL_* macros in glslDan Goodliffe2026-01-29
|
* Explicit cast to vec3 to disambiguate length/distance calcDan Goodliffe2026-01-26
|
* Fix warnings and minor tidy for GL lookupsDan Goodliffe2026-01-26
|
* Include GL_MAX_GEOMETRY_TOTAL_OUTPUT_COMPONENTS in networkCurve output calcDan Goodliffe2026-01-23
|
* Add glDebugScopeDan Goodliffe2026-01-16
| | | | | Wrapper for glPushDebugGroup/glPopDebugGroup which allows neatly grouping OpenGL calls in diagnostic tools.
