Chaco: VRML test suite

VRML test suite

This test suite contains links to a variety of VRML files, split into sections. Our hope is that the VRML community will use this repository as both a source of VRML files and as a destination for your VRML test files.

Many of the files in the test suite are "minimal", which means they don't include a camera, lights, etc. This is to keep them simple for people who want to test just one feature (like "do cubes work?"). The unfortunate side of this is that many of the models are ugly, or require you to move around before you can see much. As the Suite continues to grow, we expect that more of the files will include cameras, lights, etc.

Check out these other VRML test suites, too:

If you like, you can download the whole test suite as a zip file or as a tar.gz file.

Simple Objects

These are just the specified objects, at their default sizes (unless otherwise specified).

Cube
Cylinder
Cone
Sphere
Face A single square face, from (-1, 0, 1) to (1, 0, -1). (Includes a Coordinate3.)
Line A square line set in the default color, from (-1, 0, 1) to (1, 0, -1). (Includes a Coordinate3.)
linecolor A square line set of color (.8 .8 .8), from (-1, 0, 1) to (1, 0, -1). (Includes a Coordinate3.)

Lights

Directional A light pointing from the initial camera to the cube (so 5 of the sides should be dark). Be sure your headlight is off!
Point A point light at (2, 2, 2), shining on a red cube.
Spot

PointSet

points 4 Points in a square.

Cameras

cubeper A Cube and a PerspectiveCamera.
cubeortho A Cube and a OrthographicCamera.

Rotations

tri A 1 unit high by 3 units wide triangle with a camera.
tri2 The above triangle rotated .75 around the X axis.
tri3 The above triangle rotated .75 around the Y axis.
tri4 The above triangle rotated .75 around the Z axis.

Transforms

face-rot Several rectangles, rotated, translated, etc.
face-mat Several rectangles, moved into place with matrices. This should look identical to face-rot.wrl.

Inlines

This section tests WWWInlines of various sorts.

Minimal Just a file which inlines another file which contains a cube. You may have to move your camera back to see anything. Note that the WWWInline has a relative URL, which may fail with some viewer/browser combinations.
Minimal with an absolute URL Just a file which inlines another file which contains a cube. You may have to move your camera back to see anything. This version has an absolute URL.
Minimal with a camera The same as minimal.wrl, except that this one has a PerspectiveCamera defined.
Balls 9 balls from 3 inclusions of a file containing 3 balls. The color is varied in the including file.
bbox bboxSize test case. This file includes a radius 5 sphere from another file, but specifies the bboxSize of the included file.

Simple Textures

Each of these files contains these three lines of VRML:

                PointLight { location 2 2 2 }
                Material { diffuseColor .8 .8 .8 }
                Texture2 { filename monotex.gif }

followed by the described object.

Cube
Cylinder
Cone
Sphere
Face A textured square face, from (-1, 0, 1) to (1, 0, -1). (Includes a Coordinate3.) Since this face is perfectly square, the spec allows the texture to be mapped on in almost any way.
Face2 A textured square face, from (-1, 0, 1) to (1.1, 0, -1). (Includes a Coordinate3.) The spec gets better in this case, but is still ambiguous about where the origin of the (s,t) axis should go.
face3 A textured square face, from (-1, 0, 1) to (1, 0, -1). This version uses TextureCoordinate2, so all viewers should draw this the same.
Line A square line set, from (-1, 0, 1) to (1, 0, -1). (Includes a Coordinate3.)

Tricky Textures

repeat5 A tiled texture on a square face.
t2face A square face with a Texture2Transform'ed texture. translation is set to ".5 .5".
t2face2 A square face with a Texture2Transform'ed texture. rotation is set to .2.
t2face3 A square face with a Texture2Transform'ed texture. scaleFactor is set to "1.2 1.2".
t2face4 A square face with a Texture2Transform'ed texture. scaleFactor is set to ".8 .8".
t2face5 A square face with a Texture2Transform'ed texture. center is ".5 .5", rotation is .2.
t2face6 A square face with a Texture2Transform'ed texture. center is ".5 .5", rotation is .2, scaleFactor is "1.5 1.5".

SFImage

These files test various aspects of SFImage.

sfimage A simple SFImage. The texture is from the VRML 1.0 spec: " a 2 pixel wide by 4 pixel high RGB image, with the bottom left pixel red, the bottom right pixel green, the two middle rows of pixels black, the top left pixel white, and the top right pixel yellow."
sfimage2 Another simple SFImage. This texture comes from http://hyperreal.com/~mpesce/orrey.cgi.
sfimage3 A complex SFImage with the Chaco logo (upside-down).

LOD - Level Of Detail

Some VRML viewers don't yet support LOD, so these files may do strange things.

Minimal A red Cube far away, a Cylinder when closer, a Sphere very close.
queenbig A "queen" chess piece, varying in polygon count as you move away from it & towards it. This file contains an SFEnum with a value of "OFF", which some VRML viewers can't handle.
queenbignoenum A "queen" chess piece, varying in polygon count as you move away from it & towards it. This file does not contain the SFEnum that queenbig has.

WWWAnchor

HTML A cube with an anchor to an HTML page.
VRML A cube with an anchor to a VRML sphere with an anchor back to the cube.

AsciiText and FontStyle

Some VRML viewers don't support AsciiText, so these test cases may not display anything with yours.

TextTest Chris Marrin's excellent text test.
FontStress Various AsciiText and FontStyle tests, all in one file.

GZIP

GZIP is supported by many VRML viewers, but may not work with the one you're testing. It's also possible your web browser will give a warning dialog like "Warning: unrecognized encoding: 'x-gzip'.".

cube.wrl.gz A compressed version of the simple cube.
inline.wrl.gz A compressed file which incluees the compressed 'cube.wrl.gz' above.

Bad VRML

These test files contain "bad VRML" in that they are either non-compliant or are designed to crash VRML viewers with bizarre tests that should never be seen in a real VRML file.

ctrlzeof A cube in a file with a control-z at the end (after the terminating '}').
ctrlzmid Two cubes in a file with a control-z between them. This file gives an error with most viewers, because it's not a valid VRML file.
ctrlname A DEF name with a control-f in it. The scene should be two cubes. This is also invalid VRML, so most viewers will give a read error on it.
Recurse This file has a Cube and includes itself. Not very polite.

The VRML below here has yet to be sorted into categories above the magic horizontal line.

Chaco's VRML

Most of this is VRML we wrote at Chaco, but some of it is just local (usually tweaked) copies of other folks' VRML.

Dusk

Debugging

These files are (or were) used by Chaco for debugging our VRML viewers.
