textures (version 0.1.0)

png_plot3d: Plot a PNG bitmap in 3D

Description

This is the core idea of the textures package in minimum form: a single quad carrying a full-resolution image, with all interpolation done by the graphics engine.

Usage

png_plot3d(pngfile, dim = c(1, 1))

Value

returns a mesh3d with 1 quad and the image file textured to it, as a side effect creates a 3D interactive plot

Arguments

pngfile

path to a PNG format image file

dim

specify dimensions of quad grid see quad()

Details

Consider that the vertices on each corner can be changed by value arbitrarily, this will affect the way this will be represented geometrically and visually. If the internal mesh of the quad is denser, this provides automatic image reprojection work entirely by the graphics engine.

Examples

if (FALSE) { # interactive() && requireNamespace("rgl", quietly = TRUE)
file <- system.file("extdata/Rlogo.png", package = "textures")
png_plot3d(file)
}
