The issue is as soon as you give the models context. If it can\u2019t understand the 3D nature of a hand or the context of a situation, it will struggle to accurately recreate it.<\/p>\n<p>For example, a hand holding an object like a knife or camera, or someone making a symbol with their hand is instantly going to confuse a model that doesn\u2019t have the 3D understanding of a hand or the geometric shape of the object it is holding.<\/p>\n<p>\u201cI asked Dall-E to show a photograph of two hands with their fingers interlaced and I got some bizarre results. It showed me two wrists and a ball of fingers for one of them,\u201d says Bentley.<\/p>\n<p>\u201cBut you can understand why. It doesn\u2019t really know what it is doing, and it is just combining all these images that it has seen to meet your textual description as best as it can.\u201d<\/p>\n<p>However, it isn\u2019t just Dall-E 2 that struggles with this. Other popular image models like Midjourney and <a href=\"\/\/stablediffusionweb.com\/&quot;\" target=\"&quot;_blank&quot;\" rel=\"&quot;noopener&quot; noopener noreferrer\">Stable Diffusion<\/a> have been hit with the same impossible task of making a normal-looking hand.<\/p>\n<h2><strong>Taking a closer look at the picture<\/strong><\/h2>\n<p>While it can often feel like the images these models are creating are near-perfect, they are actually often very flawed.

morph together in these images \u00a9 Dall-E 2<\/span><\/figcaption><span class=\"&quot;im-image-caption&quot;\"\/><\/div>\n<h2><strong>The major hurdle for AI images<\/strong><\/h2>\n<p>So these models are good, great even\u2026 but they are still a long way from creating perfect images. What would have to happen to resolve this problem and finally create a hand that doesn\u2019t look like it was inspired by David Cronenberg?<\/p>\n<p>\u201cThis could all change in the future. These networks are slowly being trained on 3D geometries so they can understand the shape behind images. This will give us a more coherent image, even with complicated prompts,\u201d says Bently.<\/p>\n<p>\u201cGetting enough 3D design data could take time. At the moment, we\u2019re getting the easy results in the form of these 2D images. It is easy to trawl the internet and get a million images without the context.\u201d<\/p>\n<p>This is something OpenAI is started to work on with its\u00a0<a class=\"&quot;c-link&quot;\" href=\"\/\/www.sciencefocus.com\/future-technology\/point-e\/&quot;\" target=\"&quot;_blank&quot;\" rel=\"&quot;noopener noopener noreferrer\" noreferrer=\"\" data-stringify-link=\"&quot;https:\/\/www.sciencefocus.com\/future-technology\/point-e\/&quot;\" data-sk=\"&quot;tooltip_parent&quot;\" data-remove-tab-index=\"&quot;true&quot;\">Point-E<\/a> technology, creating a system that can create 3D models from texted prompts. While it is currently usable by the public, it is a long way from producing accurate results.<\/p>\n<p>However, when results do come, they could lead to highly detailed 3D renderings and even digital worlds. As Bentley explains: \u201cA lot of money is going into things like the <a class=\"&quot;c-link&quot;\" href=\"\/\/www.sciencefocus.com\/future-technology\/metaverse\/&quot;\" target=\"&quot;_blank&quot;\" rel=\"&quot;noopener noopener noreferrer\" noreferrer=\"\" data-stringify-link=\"&quot;https:\/\/www.sciencefocus.com\/future-technology\/metaverse\/&quot;\" data-sk=\"&quot;tooltip_parent&quot;\" data-remove-tab-index=\"&quot;true&quot;\">metaverse<\/a>\u00a0with an interest in 3D models. So it is quite possible with these combined budgets that we could see increasingly impressive 3D models created by AI.\u201d<\/p>\n<p>This is technology that could continue to improve to bigger and more impressive things. Right now we\u2019re looking at 2D created images from AI, the future could be highly detailed 3D renderings and even digital worlds.<\/p>\n<section class=\"&quot;highlight\"><div class=\"&quot;highlight__content\" editor-content=\"\"> <h4>About our expert, Dr Peter Bentley<\/h4>\n<p>Peter is a computer scientist and author who is based at University College London.
