Computer Graphics

Computer graphics encompasses the mathematical modelling, efficient processing and photorealistic rendering of virtual scenes for display on two- and three-dimensional devices. Its scope spans the construction of geometric representations—from polygon meshes and subdivision surfaces to implicit volumes—through to illumination modelling, view-dependent projection and rasterisation into pixels. Modern pipelines exploit programmable shaders on graphics processing units to execute vertex transformations, visibility determination, fragment shading and post-processing effects in parallel. Physically based rendering methods, including path tracing and Monte Carlo integration, simulate complex light transport to capture soft shadows, reflections and subsurface scattering. Increasingly, data-driven approaches harness deep neural networks and diffusion models to accelerate denoising, super-resolution, inverse rendering and zero-shot text-to-3D generation. Three-dimensional displays, from integral-imaging near-eye systems to holographic wavefront reconstruction, extend visualisation beyond traditional flat screens. Across entertainment, virtual and augmented reality, scientific visualisation and industrial design, computer graphics underpins immersive interaction and rapid prototyping by uniting rigorous geometric algorithms with high-throughput hardware architectures.

A novel near-eye volumetric system achieves video-rate full-colour three-dimensional imagery by integrating a large-area nanoimprint metalens array with a commercial microdisplay and a real-time elemental-image rendering algorithm. The design overcomes previous bottlenecks in speed and form factor, yielding a see-through augmented-reality prototype with seamless accommodation cues. In another advance, Monte Carlo frameworks have been extended to handle nonlinear state functions by projecting onto polynomial bases and enlarging configuration spaces. This method retains dimension-independent convergence and permits the direct simulation of rare events in radiative transfer, electromagnetic scattering and particulate media, broadening the suite of light-matter interaction problems amenable to unbiased random sampling without compromising computational efficiency.

A practical algorithm guarantees topologically correct intersections of B-spline surface patches under near-critical configurations. By robustly treating multiple branches, singular contacts and high-order tangencies with performance comparable to commercial geometry kernels, it preserves correct curve connectivity even when surfaces are nearly tangent. In the realm of generative content, a multi-view diffusion-guided framework completes occluded surfaces by applying score distillation sampling to normal maps rather than only colour renderings. This approach reduces artefacts and improves fidelity by aligning synthetic geometry with observed viewpoints through tuning-free consistency constraints. Elsewhere, a hybrid transformer–Fourier network interleaves fast Fourier convolution with frequency-spectrum modules to deliver lightweight single-image super-resolution. By preserving global context and high-frequency details, it reduces parameter count by over a third and accelerates inference by up to 60 percent relative to state-of-the-art transformer baselines.

Technical terms

Rasterisation: The process of converting vector-based geometric primitives into a pixel grid for display, determining which screen samples each primitive covers.

Tessellation: Dynamic subdivision of coarse geometric patches into finer polygons (usually triangles) to improve surface smoothness or adapt detail to screen resolution.

Monte Carlo integration: A stochastic sampling technique used in rendering to approximate high-dimensional light transport integrals by random path generation.

Score distillation sampling (SDS): A method that leverages gradients from a pre-trained diffusion model’s denoiser to guide optimisation of an external representation, such as 3D geometry or surface normals.

Bidirectional reflectance distribution function (BRDF): A four-dimensional function that describes how light is reflected at a surface, relating incoming and outgoing radiance based on surface microstructure.

Neural radiance field (NeRF): A continuous volumetric representation encoded by a neural network that maps spatial coordinates and viewing directions to radiance and density for photorealistic scene synthesis.
