The KashBird supports two different kinds of Cameras basically. There are many camera variations combining different options. Each camera setting can be named and registered so that you can create your own camera by combining your favorite setups.
There are several ways to select or setup the camera as shown below.(a) Select by Control BarSelect a camera from the list.
Click the switch with the camera symbol at the center of the control bar.
< Information >
If the control bar is not visible completely the bar can be scrolled by mouse drag.
(b) Select by [Setup] - [Camera].
Select the [Camera] switch on this dialog. The [Camera Setup] dialog is only for the camera location.
For normal use, panorama picture and the most beautiful picture select [Default camera], [Panoramic Camera], and [Professional Camera] respectively.
For further detailed Setup and creating a custom camera please click the [Detail>>] button.
For high end option of camera there are following functions.(1) Type- Normal(2) Terrain Quality
To simulate with normal 35 mm film size camera this option is selected. The landscape is projected on a plane. For creating a normal CG select this option. The landscape and the panorama are represented the most beautifully. As a real camera the scene is distorted in the end or corner of the picture.
This option is selected for taking a panorama picture which you need a short object lens. The landscape is projected on a Azimuth - Altitude Angle System (Cylinder). This is identical to one of the old Kashmir (Ver.3 or earlier). This projection causes no distortion even for the short object lens.
The panorama has following restrictions.
- Bank is not possible
- Clouds can not be taken.
- The texture on the near ground may be distorted.
- Round Camera
Select with panorama camera. THis option enables a 360 degree exposure which makes possible to scroll whole 360 degree angle. The quality of the picture depends on the length of the object lens. When you choose a long object a detailed panorama will be taken. But it will also take much time or may cause a memory problem if you select too long object length. The round camera has some function restrictions.
To setup whether the elevation data is used selectively. If you select "Rough" rendering will be quickly but the picture becomes rough and will have less reality.- Automatic(3) Rendering
THis option enables rough rendering in far landscape and use of all data point in near landscape. For normal use this option provides enough quality of the picture.
- All Points (x1)
All data points are used for all points.
- Rough (x2)
One data point for every two points is used.
- Rough (x4)
One data point for every four points is used.
Settings for representation- Full Z-Buffer(4) Ray-tracing
All pictures are rendered by the Z-Buffer method. Quick rendering is possible. But mirroring on the water surface and shadow representation are not possible. For a trial or if you need no mirroring it would be enough. For a wide area this option is recommended or you may have a memory problem.
- Full Rey-Tracing
The rendering is done by the ray-tracing method. Mirroring on the water surface and shadowing are possible. For a wide area you need much memory size and it takes also much time to render.
- Ray-tracing near only
For the near area the ray-tracing is used. For other far area the Z-buffer method is used. If [Automatic Setup] is checked the tracing area border is set automatically. Unchecking of this option enables you to setup the distance in manual. This option may cause a discontinuity between the ray-tracing area and the Z-buffer area. This option is not recommended for a large tilt camera angle.
These options are valid only when the rey-tracing option is selected.- Shadow(5) Register / Delete / Edit Comment
To enable shadow this option is checked. Shadow and shade are different. Invisible area ca be rendered by the Z-buffer method. Shade is the area which is dark because it is not lightened.
- Shadow of Cloud
To enable shadow of clouds this option is checked. The cloud may have to be low enough so that you can get an expected picture.
- Depth of Ray
To setup the number of the reflection / refraction this option is selected. Normally two is enough as this value. It is seldom that the value becomes more than three for landscape CG.
You can register or delete the setups into the list on the left side. Please enter your title. you can write a description of the setup by selecting the "Edit Comment". The first three characters become the camera type.
