DoGA ([do:ga] means 'Animation' or 'moving picture' in Japanese)
DOGA is a popular program among NationStates players for creating 3D artwork. It is akin to virtual LEGO in that you use pre-made 'parts' to build a model. Just as with LEGO you are only limited by your creativity in how you put those parts together. Unlike LEGO you always have enough pieces and they come in whatever color you want.
The simplest version of DOGA (L1) is still free, but you will need to pay for the more advanced versions if you wish to render images.
DOGA Hints and Tricks
Bump Mapping: Edit the desired Part Attribute and click the Texture sub-tab. Click the 'Bump' box then select the texture you want to use as the bumpmap from either Sample Textures or User Textures. Setting the Emphasis higher or lower will increase or decrease the apparent depth of the bumpmap when the model is rendered. Note that bumpmapping doesn't show up until you render the model.
Shadows: While the basic rendering engine has some very basic shadow functions you can enable full shadows by going to the Materials tab when editting the Part Attributes and check one or both of the boxes 'Drop' and 'Recieve' shadows. If you are placing something like a flag on a model you might want to just 'Recieve' shadows so that the flag appears to be painted directly on the surface instead of hovering over it.
Grid Fitting: Normally when you move an object it will snap to the default grid. You can turn this off under Settings and Grid Fitting -or- you can do it by holding 'Ctrl' as you move the part. 'Ctrl' also turns off the grid for rotation, scaling, and stretching parts.
Scaling: By holding down 'Shift' while dragging one of the scaling boxes this will force the object to scale with the same ratio along all axis. Holding down 'Ctrl' will stop this scaling from using the grid and instead allow the object to exceed the minimum size restrictions.
Preview Window: Holding down 'Shift' while the mouse is in the preview window will allow you to zoom in and out by moving the mouse up and down. 'Ctrl' will change the rotation point from the center of the grid to the current camera location. By combining these two you can 'walk' around an object.
Centering a Texture: If you are scaling a texture here is the formula to keep it centered on the part. If the new density is under 100 set the 'H' and 'V' to Negative (-) 100 - Density / 2. Example: Density of 40 would give you 100 - 40 / 2 = 30 so -30 on both 'H' and 'V'. If the density is greater than 100 the formula is Positive (+) Density - 100 / 2. Example: 140 - 100 / 2 = 20 so +20 on both 'H' and 'V' for an exact centering. You can adjust the 'V' option and the texture will stay symetrical but it will not be centered.
