#Tutorial
###The main goal of this tutorial is to show all capabilities of ... (this part will be supplemented)
The simple visualization can be made with function `main`. (this part will be supplemented as well)
```kotlin
import kotlinx.html.div
import space.kscience.dataforge.context.Context
import space.kscience.visionforge.html.ResourceLocation
import space.kscience.visionforge.solid.*
import java.nio.file.Paths
fun main(){
val context = Context{
plugin(Solids)
}
context.makeVisionFile (
Paths.get("customFile.html"),
resourceLocation = ResourceLocation.EMBED
){
div {
vision {
solid {
}
}
}
}
}
```
##Solids properties
**We will analyze which basic properties solids have using `box` solid.**
Basic properties:
1. `opacity` - It is set in `float`. It takes on values from 0 to 1, which represent percents of solid opacity. It's initial value is 1.
2. `color` - It can be specified as `Int`, `String`, or as three `Ubytes`, which represent color in `rgb`. Elementally, the solid will have `green` color.
3. `rotation` - it's the point, around which the solid will be rotated. Initially, the value is `Point3D(0, 0, 0)`
4. position, which is given by values `x`, `y`, `z`. Initial values are `x = 0`, `y = 0`, `z = 0`
Let's see how properties are set in solids.
The `small box` will have elemental values of properties. If you will not set properties, it will have the same `position`, `color`, `rotation`, and `opacity` values.
***You can see that `box` take four values. Later, we will discuss what they are doing in more detail. Now, it does not really matter.***
```kotlin
box(10, 10, 10, name = "small box"){
x = 0
y = 0
z = 0
opacity = 1 //100% opacity
color("red") //as string
rotation = Point3D(0, 0, 0)
}
```

The `big box` will have properties with custom values.
```kotlin
box(40, 40, 40, name = "big box"){
x = 20
y = 10
z = 60
opacity = 0.5 //50% opacity
color(0u, 179u, 179u) //color in rgb
rotation = Point3D(60, 80, 0)
}
```
![](../docs/images/big-rotated-box.png)
If we compare these boxes, we will see all differences.
Here is the function `main` with both boxes.
```kotlin
fun main(){
val context = Context{
plugin(Solids)
}
context.makeVisionFile (
Paths.get("customFile.html"),
resourceLocation = ResourceLocation.EMBED
){
div {
vision {
solid {
box(10, 10, 10, name = "small box"){
x = 0
y = 0
z = 0
opacity = 1 //100% opacity
color("red") //as string
rotation = Point3D(0, 0, 0)
}
box(40, 40, 40, name = "big box"){
x = 20
y = 10
z = 60
opacity = 0.5 //50% opacity
color(0u, 179u, 179u) //rgb
rotation = Point3D(60, 80, 0)
}
}
}
}
}
}
```

###Basic Solids
Now, let's see which solids can be visualized:
1) PolyLine
2) Box
```kotlin
box(50, 50, 50, name = "box") {
x = 0
y = 0
z = 0
color("pink")
}
```
![](../docs/images/box.png)
```kotlin
box(10, 25, 10, name = "high_box") {
x = 0
y = 0
z = 0
color("black")
}
```
![](../docs/images/high-box.png)
```kotlin
box(65, 40, 40, name = "wide_box") {
x = 0
y = 0
z = 0
color("black")
}
```
![](../docs/images/wide-box.png)
3) Sphere
```kotlin
sphere(50, name = "sphere") {
x = 0
y = 0
z = 0
color("blue")
}
```
![](../docs/images/sphere.png)
4) Hexagon
```kotlin
hexagon(
Point3D(25, 30, 25),
Point3D(35, 30, 25),
Point3D(35, 30, 15),
Point3D(25, 30, 15),
Point3D(30, 18, 20),
Point3D(40, 18, 20),
Point3D(40, 18, 10),
Point3D(30, 18, 10),
name = "classic_hexagon"){
color("green")
}
```
![](../docs/images/classic-hexagon.png)
```kotlin
hexagon(
Point3D(5, 30, 5),
Point3D(24, 30, 8),
Point3D(20, 30, -10),
Point3D(5, 30, -7),
Point3D(8, 16, 0),
Point3D(12, 16, 0),
Point3D(10, 16, -5),
Point3D(6.5, 12, -3),
name = "custom_hexagon"){
color("brown")
}
```

5) Cone
```kotlin
