+## VCM
+
+Текстовый формат описания 3D моделей, являющийся заменой устаревшего свойства `model-primitives`.
+
+Синтаксис:
+
+```
+@примитив атрибут (значение1,значение2,...) атрибут2 "значение3" {
+    @внутренний_примитив ...
+}
+```
+
+Аналогичная структура в XML:
+
+```xml
+<примитив атрибут="значение1,значение2,..." атрибут2="значение3">
+    <внутренний_примитив .../>
+</примитив>
+```
+
+В отличие от XML в корне может находиться несколько элементов.
+
+На данный момент существует два вида примитивов: box и rect, а также, part (описывает часть примитива, такую как, например, сторона куба).
+
+### Свойства `rect`
+
+- `from` - точка начала примитива. Пример: `from (0,0.5,0.125)`
+- `right` - вектор X, также определяющий ширину примитива. Пример: `right (1,0,0)`
+- `up` - вектор Y, также определяющий высоту примитива. Пример: `up (0,1,0)`
+- `texture` - отображаемая текстура. По-умолчанию: `$0`. Пример: `texture "blocks:sand"`
+- `region` - UV регион в границах выбранной текстуры, определяется позициями противоположных углов. Пример: `region (0,0,1,1)`
+- `region-scale` вектор-множитель для автоматически выбранного UV региона. Пример: `region-scale (0.5,1)`
+- `shading` определяет возможность затенения на примитиве. Пример: `shading off`
+- `flip` отражает UV регион по горизонтали или вертикали. Пример: `flip v`
+
+### Свойства `box`
+
+- `from` - точка начала примитива. Пример: `from (0,0,0)`
+- `to` - противоположная от начала точка. Пример: `to (1,1,1)`
+- `texture` - отображаемая текстура для всех сторон по-умолчанию.
+- `shading` определяет возможность затенения на примитиве. Пример: `shading off`
+- `delete` удаляет стороны по именам (top, bottom, east, west, north, south)
+
+### Свойства `part` (в `box`)
+
+- `tags` - определяет то, на какаие из сторон будут применены свойства. Пример: `tags (top,bottom)`
+- `texture` - отображаемая текстура. По-умолчанию: `$индекс_стороны`.
+- `region` - UV регион в границах выбранной текстуры, определяется позициями противоположных углов. Пример: `region (0,0,1,1)`
+- `region-scale` вектор-множитель для автоматически выбранного UV региона. Пример: `region-scale (0.5,1)`
