Gemtree Petr - ScreenShot
Gemtree Peter 2.50 ScreenShot is a specially modified version of the Gemtree Peter, used to generate graphics for photobanks. It allows capture content of 3D window into file with high resolution. The image is rendered and captured in parts (tiles) and stored into files scrXXXXX.tga. There are not supported 2D images in 3D window (2D crosshair, title texts), they appear repeatedly in each tile of image. The Keys:
Shift+Pause = captures the image with a width of 8000 pixels or larger (an integer multiple of half of width of 3D window). Performed antialiasing (the image is captured 2x greater).
Alt+Shift+Pause = starts sequential storage with a width of image 1920 pixels and with timing for the speed of output video 29.97 fps. Stop saving with Pause key. The sequence of TGA files can be compiled into a video using VirtualDub program.
Alt+Pause = starts sequential storage at current resolution without scaling the image, ending with Pause. Can be used for a quick preview.
Petr 2.50 ScreenShot, ZIP without installation, only alone exe (1 MB)
Petr 2.50 ScreenShot 4k, ZIP without installation, only alone exe (1 MB) - alternative saving video 4k (3840x2160), item ScrollLock can control saving video (test, set, after wait item count frames)
Example of program created with this version:
Modeller 2 - create rotated objects, 3D view can be captured using Shift+Pause.
Contains program ModellerAnim as example how to create
program in Peter for capturing animated videosequence.
Another sample program is
ScreenSaver - fly through rotated objects. In file ScreenSaver.txt there is profile
of rotated object which can be get from Modeller. File
ScreenSaver.bmp contains texture of object surface.
Texture can be in 8-bit palette format as is sample
texture (better in uncompressed form) or it can be 24-bit
RGB image. Purple color with value R=149, G=34, B=140 (or
#95228c, need to be exactly set) is transparent color -
in that place there can be seen random background color
of the object. Only background color has light and
shadow, surface color has no shadows or reflections.
Control keys:
BackSpace
- switch between IMAGE and VIDEO mode (changes window
size)
Shift+Pause - in mode IMAGE captures
image into file TGA with resolution 8000x6000 pixels (one
image can be captured a few seconds)
Shift+Alt+Pause - in mode VIDEO starts
capturing video with speed 29.97 fps (speed of capture
can be 2 shots per second, stop with Pause)
Enter - random color of background
arrows, Home, End - change speed of
camera rotations
PageUp, PageDown - change speed of
camera
Delete - stop camera rotations, in mode
IMAGE stops moving too
Insert - switch between manual and auto
control
Esc - quit the program
Pidicraft_Screenshot - cube world, with user textures and with
saving animations into video.
Petr 2.50 ScreenShot OpenGL, ZIP without instalation, just alone exe (1 MB) (and source code) - another alternative - enables only OpenGL1.1 (it has better output and textures require less memory, it can be used under Wine in Linux), therefore OpenGL 1.1 need to be selected as interface in program (autodetection does not work). ScrollLock switch controls saving video (diring wait element), Insert switch controls 4K or FullHD dimension. Rendering group is always sorted only with Z coordinate (not with distance). Generator of animations Animer was created using this version.
