Announcements

Tue 3/19 1:30am

Wrapped pixel retrieval in htonl() for compatibility when running across the net between machines with different byte orders. (Thanks Eric Tucker.)

Mon 3/18 11:20pm

• Changed -out command-line switch to -outs.
• Added rendering of scenes onto disk, using the M key. The new -outf command-line switch sets the base name of the output frame files.

Thu 3/14 7:00pm

Added primitive rendering using wireframes (activated using the w key).

Mon 3/11 4:20pm

Changed tessellation of cones and cylinders to match disc's, so that a disc may perfectly cap a cone/cylinder. (Thanks Kekoa Proudfoot.)

Fri 3/8 8:00pm

Implemented several student suggestions:

• The viewing area dimensions of MOAN can be specified from the command-line, using the switch -size. (Thanks Ju-Hsien Kao.)
• The input scene file can be reloaded while MOAN is executing, by pressing the U key. (Thanks Ju-Hsien Kao.)
• When scene files are saved, a comment line precedes the Group End line of every named group; it contains the group name. (Thanks Sam Varghese.)

Also, I fixed a bug in the interaction of scale transformations and lighting: GL_NORMALIZE was enabled (since, by default it is disabled). (Thanks Terry Jones and Kekoa Proudfoot.)

Mon 3/5 10:00pm

Re-oriented cone and disc primitives to make y their symmetry axis. (Thanks Eric Tucker.)

Mon 3/5 6:00pm

Added sample image of an articulated figure, along with a movie of the animation, to the MOAN WWW documentation.

Mon 3/5 3:00pm

Added simple scene tree example from assignment handout (simple.sc).

Mon 3/5 2:30pm

Added viewing area configuration message on top line of status bar.

Mon 3/5 2:30am

Added single view mode for user-specified cameras.

Mon 3/5 12:30am

Added disc primitive. Made cone, cylinder and line primitives symmetrically centered about the origin. (Thanks Eric Tucker.)

Sun 3/4 11:45pm

Fixed C Makefile to be compatible with new DCC raptor installation (effective 3:00pm).

Sun 3/4 10:00pm

MOAN WWW documentation completed.

Sun 3/4 6:00pm

Added code to disable editing of all parameters when the selection is changed. Changed activators for field of view to a/A from v/V. Removed -ambient command-line switch. Modified help screen to match WWW documentation more closely.

Sun 3/4 1:00pm

Changed ffloor() calls to floorf() calls for portability. (Thanks Denton Gentry.)

Sat 3/3 4:00pm

Swapped order of name and type in joint translations and cameras.

Sat 3/3 8:30am

Submission script completed and documented.

Sat 3/3 7:30am

Added C++ versions of interpolation.c and Makefile.

Sat 3/3 6am

interpolation.* renamed to interpolate.* to match assignment specs; Makefile and moan.c updated accordingly.

Thu 3/1 midnight

Assignment 3 files were installed on the Leland file system, as soon as adequate disk space was made available.
