Herramientas que nos ofrece la ventana del V-Ray frame buffer

Anteriormente, en Introducción a V-Ray, hablamos, de forma general, de los botones que componían la ventana del frame buffer de V-Ray. Hoy conoceremos todas las herramientas que nos ofrece la ventana del V-Ray frame buffer.

En primer lugar, debemos saber qué es el frame buffer. Como ya vimos en Términos más utilizados en infografía 3D, un frame es cada imagen renderizada. El buffer es la porción de memoria reservada para mantener esa imagen a la espera de ser enviada al monitor. Por lo tanto, el frame buffer es la memoria que nos almacena esas imágenes o frames. Además, nos brinda el control total sobre la salida de la imagen renderizada, poniendo a nuestro servicio herramientas con las que revisar, analizar y procesar nuestras imágenes.

Parte superior.

  1. Capas que componen la imagen.
  2. Canales RGB.
  3. Visualizar en canal Alpha.
  4. Visualizar en blanco y negro.
  5. Guardar la imagen en el disco duro.
  6. Cargar una imagen en el Frame Buffer.
  7. Limpiar el Frame Buffer, por lo que desaparecería la imagen.
  8. Duplicar la imagen, abriéndola en el Frame Buffer de 3D Studio Max.
  9. V-Ray renderiza por donde vamos pasando el ratón.
  10. Renderizar una región de la imagen.
