After you have created a model of earth by UV mapping, the next logical step is for you to want to model the solar system.
The following is a list of the models you will need to complete the project:
- Earth (we already done)
- Saturn (with rings)
- Uranus (with rings)
For an additional challenge you can make the moons of Earth, Mars, Jupiter and Saturn.
Create the SunEdit
Add a new sphere. In edit mode choose the two vertices in the poles and erase them. Now deselect all (A), and choose the upper round of vertices. Switch to orthography view and extrude approximately to where the removed vertex was, and then S + 0. Do the same thing to the other hemisphere.
select the vertices in the half middle longitude, and mark seam (ctrl+E). the picture we will use for UV mapping will be the map of the sun. search in the web: "sun map", and take the one with the bigest resulation. make UV\Image Editor window and upload the Image (introduction in the previus modul). mow choose all vertices and Unwarp (U > Unwarp). what we gona do is to make to line stright to a grid in the picture, that will make the mapping okay.
- choose one of the Longitude (use Alt+select) and scale on x 0. that make it straight. do it to all of the longitudes.
- choose one of the latitude and scale on y by zero. that make the line straight. do it to all of the latitudes.
- choose the middle line of the crowd lines and use the proportional tool to scale it on X until the lines have approximately the same betterments.
- grab and scale all vertices until it fitting to the picture.
- switch to texture drow type and watch you work. (tip: if there is not light source in the scene, you can see all the object light.)
Make the PlanetsEdit
By now you are probably thinking, "What! I need to go through all of this for each planet?" Actually, you don't. Just copy the object with the texture, switch edit mode, select all and change the picture!
*advice: put each planet in different layer.
Of course the Sun in much bigger than the Earth and other planets, but by how much? You can find additional information on the size of each planet from the following link: http://sciencenetlinks.com/interactives/messenger/psc/PlanetSize.html
The web page shows the smallest planet as 1 unit. So compare Pluto (the smallest planet aka dwarf planet) to all the other planets to gain the correct scaling ratio for each planet with respect to Pluto. Once you have created all the planets you may find the Sun is too big. The solution is simply select all the models with (A) and scale (S) them all down together.
I shure you think you need to place the planets correctly the same distances. but the problem, it is if so you will not can see more then one planet the same picture. so just place theme the right order.
