Linux 6.15 will bring graphics improvements

Linux 6.15 is currently under development with a lot of promising changes, such as better support for PlayStation 5 controllers, lots of networking changes, and much more to come. It also brings the following key graphics and chipset improvements:

  • Added support for Apple Touch Bar for M1 and M2 MacBooks using the appletbdrm driver
  • Added the nova-core driver as a skeleton Rust driver
  • Added the DPCD eDP v1.5 definition
  • Added support for B140UAN04.4, BOE NV140FHM-NZ, CSW MNB601LS1-3, LG LP079QX1-SP0V, MNE007QS3-7, STA 116QHD024002, Starry 116KHD024006, Lenovo T14s Gen6 Snapdragon
  • Added support for CSOT PNA957QT1-1, Kingdisplay kd110n11-51ie, Starry 2082109qfh040022-50e
  • Added support for Raydium RM67200
  • Added support for BOE AV123Z7M-N17, BOE AV123Z7M-N17
  • Added driver for the Apple Summit display panel
  • Added driver for Visionox RM692E5
  • Added support for GC 11.5.2 + 11.5.3
  • Added support for SDMA 6.1.3
  • Added support for NBIO 7.9.1 + 7.11.2
  • Added support for MMHUB 1.8.1 + 3.3.2
  • Added support for DCN 3.6.0
  • Added support for G200eH5
  • Added support for the MT8365 SoC
  • Added support for MT8188 with DSC compatibility
  • Added support for rk3562-mali
  • Added support for AIC200
  • …alongside other improvements for existing devices

After updating to Linux 6.15, you will notice improved graphics performance across many areas, alongside the new features that this pull request brings.

rounding and pixel-accurate image rendering are driving me slightly mad

who would've thought that it's possible for a pixel-rounded 3D position to be jittering when the camera is rotating while focused directly on that position

similarly, rasterizing an image (with bilerp) seems to generate a lot of crawling normally when the positions are not rounded

but animating with rounding enabled creates an ugly stepping effect

there are no good options

🕶️ SeeLe: A Unified Acceleration Framework for Real-Time Gaussian Splatting

arxiv.org/abs/2503.05168

arXiv logo
arXiv.orgSeeLe: A Unified Acceleration Framework for Real-Time Gaussian Splatting3D Gaussian Splatting (3DGS) has become a crucial rendering technique for many real-time applications. However, the limited hardware resources on today's mobile platforms hinder these applications, as they struggle to achieve real-time performance. In this paper, we propose SeeLe, a general framework designed to accelerate the 3DGS pipeline for resource-constrained mobile devices. Specifically, we propose two GPU-oriented techniques: hybrid preprocessing and contribution-aware rasterization. Hybrid preprocessing alleviates the GPU compute and memory pressure by reducing the number of irrelevant Gaussians during rendering. The key is to combine our view-dependent scene representation with online filtering. Meanwhile, contribution-aware rasterization improves the GPU utilization at the rasterization stage by prioritizing Gaussians with high contributions while reducing computations for those with low contributions. Both techniques can be seamlessly integrated into existing 3DGS pipelines with minimal fine-tuning. Collectively, our framework achieves 2.6$\times$ speedup and 32.3\% model reduction while achieving superior rendering quality compared to existing methods.

managed to get the building into the main menu, with some hacky lighting

(not the final version for the upcoming update but close enough)

this is about as far as I'm inclined to take things in the near future

in the process of assembling the scene however, found a bunch of issues with floor plan editing and the transform gizmo, will need to address them sometime soon

should also rethink lighting for more open spaces like this
