GPU-based Appearance Preserving Trimmed NURBS Rendering

  journal={J. WSCG},
Trimmed NURBS are the standard surface representation used in CAD/CAM systems and accurate visualization of trimmed NURBS models at interactive frame rates is of great interest for industry. To support modification and/or animation of such surfaces, a GPU-based trimming and tessellation algorithm has been developed recently. First, the NURBS is approximated with a bi-cubic hierarchy of B´ ezier patches on the CPU and then these are tessellated on the GPU. Since this approach only took the… 

Direct evaluation of NURBS curves and surfaces on the GPU

This paper presents a new method to evaluate and display trimmed NURBS surfaces using the Graphics Processing Unit (GPU), which incorporates dynamic Level of Detail (LOD) for real-time interaction at different resolutions of the N URBS surfaces.

A New Approach to Accelerate NURBS Surface Rendering on GPU

According to the experimental results, NURBS surface rendering with less meshes can still produce the evaluation of the exact surfaces and the shading effect also can be calculated by using the exact positions and normal vectors.

Tessellation and rendering of trimmed NURBS models in scene graph systems

A robust tessellation method for individual trimmed NURBS surfaces is presented which guarantees a geometric error threshold between the polygonal representation and the original analytic surface, and an occlusion culling method is presented, which performs well even in extremely low depth complexity situations and performs at least on par with state of the art occluding methods for high depth complexity scenes.

It is shown that efficient computation of positions and normal vectors for B-spline surfaces can be done on GPUs by applying ideas about the extension to NURBS and trimmed surfaces.


The key features of the new breed of GPU that are significant for the CAD researcher and commercial developer are outlined.

Projecting tetrahedra without rendering artifacts

This work identifies linear interpolation in screen coordinates as a cause for significant rendering artifacts and implements the correct perspective interpolation for the PT algorithm with programmable graphics hardware and demonstrates how to use features of modern graphics hardware to improve the accuracy of the coloring of individual tetrahedra and the compositing of the resulting colors.

Real‐Time Shape Editing using Radial Basis Functions

Techniques which allow us to use triharmonic radial basis functions for real-time freeform shape editing are presented and an incremental least-squares method enables us to approximately solve the involved linear systems in a robust and efficient manner.

Hardware-accelerated volume and isosurface rendering based on cell-projection

Two beneficial rendering extensions to the projected tetrahedra (PT) algorithm proposed by Shirley and Tuchman (1990) are presented, compatible with any cell sorting technique, for example the BSP-XMPVO sorting algorithm for unstructured meshes.

Smart Hardware-Accelerated Volume Rendering

This paper demonstrates how to merge the most important extensions of the original 3D slicing approach, namely the pre-integration technique, volumetric clipping, and advanced lighting, and proposes a hardware-accelerated ray caster which is able to perform over-sampling only where needed and to gain additional speed by early ray termination and space leaping.

Hardware support for adaptive subdivision surface rendering

This paper presents a meshing scheme and new architecture for the implementation of adaptive subdivision of triangular meshes that allows for quick access using a small memory making it feasible in hardware, while at the same time allowing for new vertices to be adaptively inserted.

This paper describes volume ray-casting on programmable graphics hardware as an alternative to object-order approaches, and exploits the early z-test to terminate fragment processing once sufficient opacity has been accumulated, and to skip empty space along the rays of sight.

This paper presents a hardware-accelerated solution that further improves the extraction performance of isosurface geometry in a fragment program by rendering only a single screen-sized quadrilateral.

Real‐Time Consensus‐Based Scene Reconstruction Using Commodity Graphics Hardware †

The heart of the method is to use programmable Pixel Shader technology to square intensity differences between reference image pixels, and then to choose final colors that correspond to the minimum difference, i.e. the most consistent color.
