NVIDIA GeForce 256 Review
Indy3D is an OpenGL MCAD benchmarking application and is described as follows:
Indy3D (TM) is an application-focused OpenGL® hardware performance and image quality benchmark for Mechanical Computer-Aided Design (MCAD), animation and visual simulation professionals. Indy3D provides a fast, easy-to-use interface for measurement of hardware performance based on typical application use in specific markets.
Indy3D requires no knowledge of 3D rendering to run and interpret benchmark results. To give an overview of Indy3D, I've copied the following information, some of which appears in the FAQ.
Who designed Indy3D?
Indy3D was designed by SENSE8. The data used in the MCAD test was created by Engineering Animation Inc., and the data used in the animation test was created by Westwood Studios.
What does Indy3D measure?
Indy3D is organized into three sets of tests: application, quality and primitive. There are four application tests (MCAD40, MCAD150, animation and simulation), one quality test, and three primitive tests (polygon rate, fixed rate and fill rate).
The tests are designed for 3D professionals who work with models of 10,000 + polygons and for whom superior 3D frame-rate and response time must be delivered with exceptional image quality.
Indy3D specifically stresses 3D hardware for rendering performance and image quality. The systems appropriate for Indy3D are medium to high-end PCs and workstations with a minimum memory of 128 MB.
Describe the Applications Tests
There are four applications tests: MCAD40, MCAD150, animation and simulation. Each test is composed of scene data designed to represent typical use in targeted markets.
MCAD40 & MCAD150
The MCAD tests display an engine database provided by Engineering Animation Inc. and created using Structural Dynamics Resource Corporation’s (SDRC) I-DEAS Master Series. The MCAD40 test consists of approximately 42,267 meshed, z-buffered, Gouraud-shaded, lit polygons rendered in a 1024 x 768 x 24 window (1024 x 768 pixels and 24-bit color).
The MCAD150 test consists of approximately 150,248 meshed, z-buffered, Gouraud-shaded, lit polygons rendered in a 1024 x 768 x 24 window (1024 x 768 pixels and 24-bit color). Both tests measure the average frame-rate over 125 frames while the engine "tumbles." One-third of the frames are rendered as anti-aliased wireframe, and the other two-thirds as Gouraud-shaded polygons.
The animation test illustrates a human animation via a "walking man" figure created by Westwood Studios. Each figure consists of 22,342 meshed, z-buffered, Gouraud-shaded, bilinear filtered, fogged, lit polygons. The character’s motion is created from six separate frames of animation. The image is rendered in a 1024 x 768 x 24 window, and the test measures the average frame-rate over 245 frames while sequentially cycling through the animations.
The simulation test is a sailboat, designed by SENSE8, moving through the San Francisco Bay. The default test consists of 7,260 meshed, z-buffered, Gouraud-shaded, translucent, fogged, trilinear filtered, MIP mapped, lit polygons rendered in a 1024 x 768 x 24 window. The simulation test measures average frame-rate over 225 frames while running boat and wave dynamics with a viewpoint circling the boat.
