帮助使用 rgl 包

发布于 2024-10-20 01:39:21 字数 1822 浏览 4 评论 0原文

我使用选项 --disable-libpng 安装了 rgl 软件包。我尝试生成 3D 散点图,但它崩溃了。请帮助我解决这个问题

这是我正在运行的代码

library(rgl)
open3d()
x <- sort(rnorm(1000))
y <- rnorm(1000)
z <- rnorm(1000) + atan2(x,y)
plot3d(x, y, z, col=rainbow(1000))

它崩溃并显示以下消息

 *** caught segfault ***
address (nil), cause 'memory not mapped'

Traceback:
 1: .External(rgl_par3d, args)
 2: par3d(skip)
 3: plot3d.default(x, y, z, col = rainbow(1000))
 4: plot3d(x, y, z, col = rainbow(1000))

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace

我能够从 R:从 x、y、z 绘制 3D 表面

这是代码

x <- seq(-10, 10, length.out = 50)
y <- x
rotsinc <- function(x,y) {
    sinc <- function(x) {
        y <- sin(x)/x;
        y[is.na(y)] <- 1;
        y
    }
    10 * sinc( sqrt(x^2+y^2) )
}
z <- outer(x, y, rotsinc)

surface3d(x, y, z)

我尝试了 demo(rgl),它也因类似的消息而崩溃。我想生成 3d 绘图,您推荐哪个其他软件包?格图?

I installed rgl package with the option --disable-libpng. I tried generating a 3d scatter plot and it crashes. Please help me in resolving this

This is the code i am running

library(rgl)
open3d()
x <- sort(rnorm(1000))
y <- rnorm(1000)
z <- rnorm(1000) + atan2(x,y)
plot3d(x, y, z, col=rainbow(1000))

It crashes with below messages

 *** caught segfault ***

Traceback:
 1: .External(rgl_par3d, args)
 2: par3d(skip)
 3: plot3d.default(x, y, z, col = rainbow(1000))

Some more info:

I am able to generate a surface plot from some code in R: Plotting a 3D surface from x, y, z

Here is the code

x <- seq(-10, 10, length.out = 50)
y <- x
rotsinc <- function(x,y) {
    sinc <- function(x) {
        y <- sin(x)/x;
        y[is.na(y)] <- 1;
        y
    }
    10 * sinc( sqrt(x^2+y^2) )
}
z <- outer(x, y, rotsinc)

surface3d(x, y, z)

I tried demo(rgl) and that is also crashing with similar message. I want to generate 3d plots, which other package do you recommend? ggplot?

rgl 包通过其驱动程序利用显卡中可能的硬件加速。

不幸的是,这完全取决于驾驶员。我多年来一直使用 rgl 进行动画可视化——参见例如 < a href="http://dirk.eddelbuettel.com/code/rquantlib-rgl.html" rel="nofollow">2005 年期权分析表面的可视化——我可以保证你会因为它而崩溃在某些机器上没有充分的理由,而在其他机器上运行。在做出任何确定的结论之前,您确实应该尝试使用不同的驱动程序在不同的机器上。

计算机使用硬件,有时硬件也会起作用。我可以在我的一台机器上很好地执行你的代码。另一种是双屏,因此没有 GL 扩展,所以不会。我有没有提到硬件咬合?

The rgl package makes use of possible hardware acceleration in your graphics card via its driver.

This is unfortunately entirely dependent on the driver. I have been using rgl for animated visualization for a number of years---see eg this visualization of option analytics surfaces from 2005---which I can assure you crashed for no good reason on some machines and runs on others. You really should try on a different machine with a different driver before making any firm conclusions.

Computers use hardware, and sometimes the hardware bites. I can your code fine on one of my machines. Another is dual-screen and hence without GL extension so it won't. Did I mention hardware bites?

我在我的系统上测试了完全相同的代码,它运行得很好。

无论问题是什么,它们可能已经得到解决。

测试 1:

library(rgl)
demo(rgl)

测试 2:

library(rgl)
open3d()
x <- sort(rnorm(1000))
y <- rnorm(1000)
z <- rnorm(1000) + atan2(x,y)
plot3d(x, y, z, col=rainbow(1000))

我的系统是运行 R v2.14.2 的 Windows 7 x64。在两个 IDE 下进行测试,即 Revolution R 和 RStudio。

在此处输入图像描述

I tested the exact same code on my system, and it worked perfectly.

Whatever the issues were, they have probably been fixed.

Test 1:

library(rgl)
demo(rgl)

Test 2:

library(rgl)
open3d()
x <- sort(rnorm(1000))
y <- rnorm(1000)
z <- rnorm(1000) + atan2(x,y)
plot3d(x, y, z, col=rainbow(1000))

My system is Windows 7 x64 running R v2.14.2. Tested under two IDEs, namely Revolution R and RStudio.
