The Visual Asset Creation Process - Part 2

Posted On Thursday, November 19, 2020

Note: This blog has previously been published on www.tacton.com. The author is Marco Lang, Tacton’s Senior Visualization Product Manager. Marco has more than 10 years’ experience working with visual asset creation, and configuration at Lumo Graphics, and now Tacton. In case you missed it check out the first installment of Visual Asset Creation here.

Optimizing visual asset creation a definition
Optimization refers to the process of finding a trade-off between Visual Fidelity, download speed and Rendering performance.

CAD 
In modern engineering design, nearly all 3D geometries are created by computer-aided design (CAD) systems. And those geometries are the natural starting point or input for creating Visual Assets for a 3D real-time visualization.

B-Reps and NURBS 
Boundary representations (B-Rep) are the primary method of representing modeled objects in those CAD systems. The mathematical description of curve and surface elements can vary but they are usually given in parametric forms represented by non-uniform rational B-splines (NURBS).

The main advantage of this representation is the ability to compactly describe a surface of almost any shape and store it in an efficient way. Additionally, the underlying math calculates an accurate definition of the surface shape independent of the distance the surface is examined. They do not have any pre-defined “resolution”.

The CNC machine tools that create the tooling for final products work from these accurate, smooth NURBS data. 

Tessellation 
Although NURBS are ubiquitous in the CAD industry, there is currently no built-in hardware support for displaying NURBS surfaces. To be displayed in a 3D application, NURBS surfaces need to be translated into meshes (polygons, edges, vertices), the native language of modern graphics cards. Graphics Processing Unit (GPU) pipelines are very efficient in processing triangles and they do not work properly with parametric surfaces.

A Mesh Surface 
A mesh is composed of multiple connected polygons, or triangles, forming a mesh surface that is understandable by a GPU, to be rendered in a 3D application. The number of triangles in the polygonal representation depends on accuracy used when approximating the original precise B-Rep representation. This process of taking the continuous, mathematical equation of a surface and approximating it with polygons is called meshing, triangulation or tessellation.

Since the direct evaluation of NURBS surfaces on the GPU is a highly complex and computationally intensive task, they are usually converted in simpler surface descriptions and tessellated on the CPU (Central Processing Unit) as a pre–processing step. Afterward, the set of generated triangles is sent to the GPU.

The resource demands (CPU, GPU, Memory) to execute a dynamic re-tessellation at every frame on top of all other relevant tasks necessary for an interactive real-time visualization are simply too much for an average consumer device. Therefore, tessellation is not done on the fly while the 3D real-time visualization is running, it is done as a pre-process upfront. 

Simplification 
It is important to know that when using triangles to approximate smooth edges and 3D it is not possible to achieve the perfect smoothness of an image initially created in NURBS. Unless a very high number of triangles is used, relating to performance issues on the other side. Removing, combining or simplifying non-visual elements from CAD files is crucial for generating high-performance and high-quality visual assets. Optimizing visual asset creation is a key measure of success for any visual configuration project.

Why use CPQ?

Posted On Monday, August 12, 2019


As the product portfolio grows many companies choose to use a CPQ system. A typical CPQ-user works for a company that offers a very wide range of products or services. The sales representatives (and to be honest usually others in the staff as well) have a hard time managing product prices and product dependencies. The products sold often have many options with critical technical/commercial dependencies.

CPQ software is useful by companies that need to quickly calculate prices. If a sales representative needs to quickly prepare a quote for a customer, the CPQ software automatically sums up all important information. This means that the representative can produce the quote and come back to the customer far quicker. Time is an important differential factor for all companies, regardless of whether the company works in faster or slower markets. Speed ​​is always important.

Global companies, large and small, use CPQ to quickly and effectively send pricing information to partners and customers. This means that customers can get the information right when they need it.

CPQ software is an effective way to unify how the products are presented to the customer. By using an automated tool for quote documents product can be presented in a consistent way and critical information is never missed due to human errors.

Studies show that the companies that respond the fastest have the greatest chance of finally winning the deal. This means that the speed offered by a CPQ system can have a major impact on the company's bottom line results.

In the past only large corporations could afford to use CPQ, but nowadays we see a big expansion of CPQ in small and medium sized business.
