Basx3D

 Basx3D - 3D the HTML WayThe initial version of Basx3DTM 3D the HTML Way has been released. This version is pre-alpha and is released to assist in the development of the next release of X3D V4. Basx3DTM is a 3D scene builder using declarative 3D nodes.

Perspective vs. Orthographic Cameras

This set of examples will use the first scene. It is real simple (in terms of elements), but it is sufficient to illustrate the projection issues. For the purposes of this discussion assume that the display screen is sufficiently large to show everything that is desired to be displayed. Also assume that the rendering software does not enlarge the displayed scene to fit the screen.

Proposed X3D Profile: Static Model

In the marketplace of file formats for 3D content, X3D has a tremendous advantage over all other formats by nature of its ISO Standardization, openness, and compatibility over 20 years. There are other formats that meet one or more of these features, including OBJ and FBX; however, X3D has not been a dominant or even significant player in the marketplace.

Model Archive Format for X3D

Recently there has been discussion about the suitability of various 3D formats as an archive format, especially for models. There are formats that have been around a long time (OBJ, FBX, X3D), those that are optimized for delivery (glTF), those that are widely used in existing tool chains (OBJ and FBX), plus a number of other criteria and formats including tool-specific (Blender, Maya, etc.). The most widely used format is FBX and any format that seeks to supplant it needs to offer at least as much capability as that one.

glTF/X3D Comparison

WIth 3D/VR becomming practical in the web browser there are a lot of questions concerning the right format to use for various situations. This post looks at two model formats - X3D and glTF. Both formats support full geometric surface modeling, but there are differences between these formats for some specific areas.
