some misc tips and tricks

Getting started in Kerkythea

originally written for Kerkythea release 1.3.02.adapted for

the new release called KT2007 ( version 1.41 )

With the new release of KT2007 Kim Frederik published an excellent pdf-tutorial

find it here .

I will adapt this step by step tutorial to reflect the new release.

manandmouse

Fire up Kerkythea...

New in the interface:Textmenubar: Insert and Tools-menu,

Rightwindowpane: Material Browser and Quick View

quick icons: select, rotate, pan, roll, zoom | reset, cycle, top, bottom, front, back, left, right|image, render

objects-list:(outliner)

-3D-objects

-lights

-camera's

sceneview

window

use either the folder -icon (quick-icon/-button)

or File: Open

to open a 3D-format. Any texturemaps used in the scene should reside in that same folder .

use the File Filter:-arrow to choose the default KT xml-format or other :

*.3ds or *.obj (both have some issues) or *.sia (=Silo)

quick buttons: select, rotate, pan, roll, zoom | reset, cycle, top, bottom, front, back, left, right | image, render

circle of progress

-lights

-camera's

After importing/opening: outliner and sceneview (closed MaterialQuickView-pane)


14 3/1/2010 21:39



next: push the Reset button

Now you can use the mouse-scrollwheel to move (zoom) in or out

of the current view

Next push the rotate-button


14 3/1/2010 21:39



Rotate as you like with the Left Mous Button (LMB)

The Right Mouse Button (RMB) always pans in every mode. Find a satisfactory Point Of View.

When you are satisfied it is time to add a camera. (now in the insertmenu )

accept or change the default name

In the outliner-list of objects on the left you find your camera


14 3/1/2010 21:39



LMB to select the camera RMB-click Go to View/Follow

In Active Cameraview you see the Sceneviewpane: a green dotted rectangle representing

thecameralimits . Also now a camerasymbol and a slider have appeared.


14 3/1/2010 21:39



I changed from camera to Frontview keyboard 5

you see the camera is still selected (select or unselect any object bij doubleclicking it in the objectslist )

handles/arrows allow to translate (move and rotate) the selected (camera-)object,

and for camera's and light also the target.

But hit the Escape-button first to switch from rotation-mode to selection-mode if you want to

move the camera.

keyboard D centers the selected (camera)

Use mousewheelscroll to zoom

and RMB to pan/position the view so you can translate the camera


14 3/1/2010 21:39



Moving the camera

In topview (keyboard 1) it is clear the camera is positioned much too high.


14 3/1/2010 21:39



So move the camera by using the handles/arrows.

Use the cycle-button at anytime to go to cameraview(s)

Instead I choose to add a new camera after using RMB to move/pan.....

.

As my object came in flipped the groundgrid appears to the right.

Go to Edit: Select All to rotate: use the ring(s) around the handle-/arrow(s).

More instructions on translating and scaling objects can be found in Clipi's tutorial

for release 1.3.01

Find it at the tutorials-section at

Kerkythea Home

GUI Tutorial by Clipi

This is a zipped tutorial (~5.8Mb) that shows the new GUI of release 1.3.01,

including object manipulation, light and camera setup, material editor,

basic render settings and many more. Requires Macromedia flash player.

Magnificent and a MUST for a starter. Thanks Claudio :)

Several other interesting tutorials are around there too!

So now a lightsource is needed.

As this is a outdoorscene only a sun is needed

Go to Menu:Settings: Sun and Sky....


14 3/1/2010 21:39



choose a location, date and time adjust it for G(M)T :

Next

choose a Sky Type ( I chose Physical Sky ) adjust Intensity and or Turbidity: Finish.

About sun and sky settings and turbidity find an interesting paper here

Next step is (test-)rendering:

I opened a renderwindow ( 4th button from the right )

pushed the renderbutton ( 3d button from the right )choose a camera(if you have got several or the current view,

a resolution and a rendersetting:


de 14 3/1/2010 21:39



the default choice ## custom settings ##

will be the same as 01. Ray Tracing - Quick

(as you have not as of yet changed anything in the rendersettings)

So try out: 05. GI-Quick

while raytracing is progressing try out a few of the tonemapping-options

adjusting the wheels you see immediate results

above is a render using setting 10. GI + Caustics - Medium


de 14 3/1/2010 21:39



and this a render with camera 2 is using setting 05. GI - Quick

The higher the number of the rendersettings

the more time the rendering will take.

Save the rendered image as often as you like with different tonemappingvariations,

under different names of course .

===========================

To get an idea of what you have done sofar in rendering:

Go to: WindowConsolelog

Click LMB in the log

Ctrl + A: selects al the text

Ctrl + C: copies it to the clipboard

Create a new text-document, open it

Ctrl + V: will paste the log text:
