Maya Quad Draw - and Relax (tool)

Ha! Maya's Relax tool, in Quad Draw mode.....made my quads all neat and tidy...and relax...ahhhh

Ice Man below, ready to be duplicated, merged and become transparent!

Input Read command and Camera Tracker...

Number of features 600

Feature separation 6

Select frame range eg. frames 50 - 300

Track

Once tracked, if there are any moving objects, such as people or cars, then remove those trackers manually.

Solve

Error value of below 1 is required.

The green markers are shown top left.

Any markers shown as red are rejected

Orange are to be solved.

The graph top right allows for the slider inputs to change the maximum error value. Tweak repeatedly until the error value is less than 1.

Hover mouse over view panel (top left) of the workspace and press 'TAB' to switch between 2D and 3D views

3D view showing Camera tracker cloud (white blob markers in 3D environment)

To import into Maya, in order to insert 3D objects that are embedded and move seamlessly within the scene, a scale and an origin need to be set; plus a selection of markers showing the ground plane need to be established.

To set origin in 2D viewer

Right click on a single marker on the ground

Select 'ground plane'

Select 'set origin'

To set scale:

Select one marker, SHIFT and click another

Right click

Select scene

Add

Scale distance (set scale dimension to the same as a known distance within the scene. In this case a paving slab of 40mm)

Magenta markers shown below in the 3D view, indicate the camera tracker markers that were selected on the ground plane.

Select markers on the ground

Right click

Ground plane

Set to selected

To test that the camera tracking, lens distortion correction etc are all working well, place a 'card' into the scene.

Select tracker

Create

Card

'TAB' key and Scanline Renderer node to toggle between 3D and 2D views

Card placed and rotated.

Apply texture if necessary with TAB key 'checkerboard'

Send Camera and locator to Maya

Select Scene 1 (shown as red circle in node graph below)

TAB key

Write geo 

Double click 'write_geo' node

File (black folder icon similar to file folders in attributes box in Maya)

Name file 'tracked_camera.fbx

In the options box (5 options, Geometries, Cameras, Lights, Axies, Point Clouds) just select cameras and point clouds.

Execute - select frame range

Open Maya
Set frame rate to 25 fps
Set project etc
File import 'tracked_camera.fbx
Can take a while as it imports a camera every frame, and each frame is key framed

Quad Draw practice

More practice with the Quad Draw tool; and following the tutorial and examples of good geometry around the eyes, nose and mouth....

Retopology practice and quad draw

Practicing today with retopology and the quad draw tool...
The eye shape is coming along, but I need to practice doing good loops around the mouth...

Re-group in more ways than one!

Reflective practice; examining unconscious themes in design development

Whilst eating a cake in the Grad Centre today, I noticed my research poster on the wall....I was struck by the orange guy on the bottom left of the poster...

I had literally done a material finishes test on my ice man model, about 30 mins before in the 3D lab, using the 'orange reflective' finish to see how it would look...

Interesting to see how many creative ideas from my first film concept (a character trapped in a camera negative, escaping to the light) have translated and adapted into Thaw.

The emotional theme is the same; and fascinating to see how many visual references are similar, and that I have unconcsiously carried through...

I think the Research Poster embedded some deep ideas and challenged me to be deliberate in my creative choices

Orange Reflective finish test in Zbrush

Final film, original concept idea...

Experimenting with Material finishes in Zbrush

Experimenting with materials in Zbrush; to give me some inspiration and some ideas for how this model and it's features will register and look in a glossy reflective finish

Dam_Standard and Move Brushes in Zbrush

Playing with the Dam_Standard and Move brushes in Zbrush.

My ice man material will be similar to transparent glass and I've deliberately avoided using lip sync, dialogue or eyeball animation....the net result being that my model has no internal mouth or eye geometry (as this would show up when the model is transparent)
