I3DCONVERTER EXPORT FILE EXTENSIONS FOR FREE

You can search the web for free 3D models, there are lots of paid and free models available. COLLADA files can be edited with 3D modeling programs or loaded into realtime GIS systems (such as GeoFusion) or viewed in a standard web browser using WebGL. Eventually, add track animation, morphing, nurbs, particles, shaders, geolocation, tags, etc. Initial version will transcode each node to a simple mesh object (by converting mesh verti from model space to world space to create a flattened world coord scene.) Later, we plan to map our topo hierarchies to COLLADA kinematics tree structures with closed ( link) loops. At this time, we only import geometry and its texture map, so 'GTXXXXXXXXXX' are the current default flags.įuture feature to EXPORT entire scene to a COLLADA file. See np_texture table for image processing: crop, scale, rotate.įuture planned import flags are 'GTKSNMPGLCAT' for: Geometry, Textures, Kinematics, Shading, Nurbs, Morphing, Particles, Geolocation, Lights, Cameras, (track) Animation and Tags, Bind (textures), Use (materials), Hyperglyphs (hierarchy from models scene), Lines, Points (default is off, need ON for point cloud data). Lastly, it searches the default ' usr/global/images' texture folder.Then it checks if the texture is in the same folder as the models file.First it tries the path specified in the 3D models file.Note that at draw time, grid objects are scaled to fit the grid extents (and it is assumed the geometry is normalized). Tip: You can re-generate the (bounding box) scale and (geometric) center by setting the x/y/z scale to zero (in np_models table). np_models_ai_ps Calls aiSetProp.Str(), note that the format is ''AI_PROPERTY_AS_STRING','Forty Two''.np_models_ai_pf Calls aiSetProp.Float(), note that the format is ''AI_PROPERTY_AS_STRING',42.0'.np_models_ai_pi Calls aiSetProp.Int(), note that the format is ''AI_PROPERTY_AS_STRING',42'.

antz3d binary cache file (during import).

np_models_flags antz models import flags eg, 'H.' Converts the models scene hierarchy to a forest of hyperglyphs OR 'EH' exports.

*Note that global default settings for models are set in the np_globals table, but the flags can also be overwritten by np_models table on a per node basis:

np_models_flags our import flags filter, eg: 'MT.' will load (only) meshes and textures.

np_ai_pflags aiImport property flags (uint32).

saving the dataset will export the models as a binary *.antz3d (our mime type).

object the aiNode name (object) name in the models scene file.Īttributes that are global to the models scene (set by the scene root (parent) object, children are ignored).

ai_mesh_id perhaps redundant to ainode_id (unless we split each node mesh into a geo).

ai_node_id needed if building hyperglyph trees with themodels scene nodes.

smooth Smoothing angle - ***perhaps do this globally with np_models_ai_pf().

scale XYZ is auto-normalized to fit into a 2 unit cube (-1 to 1).

rotate XYZ is manually set in the np_models table using KML Model Orientation.

center XYZ is auto-calculated using a bounding box.

texture_id links texture map files using the np_texture table.

topo_id defines topology and (if missing vertex normals) type of texture coords.

geometry_id per object, starts at 1001 (lower id's are reserved for primitives).

parent_id specifies the models_id object hierarchy, 0 for root objects.

np_models_id row id is referenced by parent_id.

At this time we support basic geometry mesh hierarchies and a single texture map per models file. You can also use the File Dialog ('L' key) to load models and auto-assign to the current node(s).

Models placed in the ' usr/global/models' folder are added to the geometry_id ('O' key) list at startup. 3D Models (3DS, OBJ, STL, PLY, COLLADA.) are IMPORTED using the ASSIMP library:
