WHAT IS TEXT TO IMAGE?


Text-to-image models are an exciting breakthrough for architects and designers. These models use deep neural networks to generate images that match natural language descriptions. They work by combining a language model that transforms input text (prompt) into a latent representation with a generative image model that produces an image based on that representation. The best models are trained on massive amounts of image and text data scraped from the web, allowing them to produce outputs that approach the quality of real photographs and human-drawn art.


Another approach involves training a model on a large set of images, each captioned with a short text description. The model then learns how to convert pure noise into a coherent image from any caption. This technology provides architects with a powerful tool for visualizing designs and communicating their ideas to clients.

MIDJOURNEY


Midjourney is an independent research lab based in San Francisco that explores new mediums of thought and seeks to expand the imaginative powers of the human species. The company was founded by David Holz, and its mission is to create innovative technologies that inspire and empower people to think creatively and explore new ideas.

One of Midjourney's most notable projects is an artificial intelligence program called Midjourney AI, which is an interactive chatbot that generates images from natural language descriptions, or "prompts". Architects, designers, and other creatives can send commands and requests to the AI via the popular platform Discord, and it will produce images based on their inputs. This service is designed to help people visualize their ideas and bring their projects to life in a new, innovative way.

Overall, Midjourney is focused on pushing the boundaries of what's possible in the realm of creative expression and intellectual exploration. The company is dedicated to using technology to enhance human potential and help people think more creatively and expansively.

DALL-E


DALL-E is an artificial intelligence program developed by OpenAI that is capable of generating high-quality images from textual descriptions. Specifically, it is a neural network trained to generate images using a combination of natural language processing and computer vision techniques. The name "DALL-E" is a combination of the artist Salvador Dali and the character WALL-E from the eponymous Pixar movie.

What sets DALL-E apart from other image-generating AI systems is its ability to create unique and complex images from scratch, based on textual input. For example, given a description like "a green armchair in the shape of an avocado", DALL-E can produce a photorealistic image of the described object that looks like it could exist in the real world.

DALL-E's capabilities have potential applications in a variety of fields, including art, design, and advertising, as well as in the creation of virtual and augmented reality experience

STABLE DIFFUSION


Stable Diffusion is a machine learning algorithm developed by OpenAI that is used for natural language processing tasks such as language modeling, text classification, and question answering.

What sets Stable Diffusion apart from other machine learning algorithms is its ability to handle long-term dependencies in text, meaning it can understand the relationships between words and phrases that are separated by long distances in a sentence or paragraph. This makes it well-suited for complex natural language processing tasks, such as language translation or summarization.

Stable Diffusion is a highly flexible and adaptable algorithm that can be fine-tuned for a wide range of natural language processing tasks, making it a powerful tool for researchers, developers, and data scientists working in the field of artificial intelligence.

PROMPTING



WHAT IS PROMPTING AND HOW TO WRITE ONE?


Prompting is the newest and most extreme form of transfer learning, allowing users to leverage the power of pre-existing models to generate images that meet specific requirements. Each request for an image can be seen as a new task for the model, which has been trained on a vast amount of data. While this technology has democratized transfer learning, it is not always effortless. Writing effective prompts can require as much work as learning a new skill or hobby. Nonetheless, architects and designers can now create stunning visualizations with greater speed and accuracy than ever before.


Did you know you can actually make ChatGPT write your prompts in any format? In the following example, we will indicate the parameters and make ChatGPT write us image prompts.


ChatGPT Prompt:


Please create a table that breaks down an architectural photography composition into the following key elements, where each of these key elements is a column : Composition, Architecture, Camera Angle, Architect Style, Material, Camera Angle and Features, Textures, Detail, Color Palette, Lighting, Location, Time of Day, Mood, Render Engine,

Fill the table with 10 rows of data, where:
Composition = "Architectural Photography,"

After the creation of the table, you can ask to make each row as a sentence with the aspect ratio you wish.


"Please write each row as a comma-separated sentence. Append each sentence with —ar 16:9"

POINT-E


OpenAI, has recently open-sourced Point-E, a new machine learning system that generates 3D objects from a text prompt. Instead of creating 3D objects in the traditional sense, Point-E generates point clouds, a set of data points in space that represents a 3D shape. Although this approach is more computationally efficient, it has its limitations in capturing an object’s fine-grained shape or texture. To overcome this limitation, the Point-E team trained a separate AI system to convert the point clouds to meshes. This new tool can produce 3D models in one to two minutes on a single Nvidia V100 GPU.


Point-E is a successor to Dall-E 2, which creates high-quality images from scratch. Point-e takes things one step further, turning images into 3D models. It works in two parts: first, by using a text-to-image AI to convert a text prompt into an image, and then using a second function to turn that image into a 3D model. Unlike a traditional 3D model, Point-E generates a point cloud, which then goes through a second step to convert it into a mesh. The end result is a 3D model that better resembles the shapes, molds, and edges of an object. Although Point-E generates a lower-quality image, it is still an impressive tool that expands the possibilities of text-to-image technology.

ControlNET


As architects, we understand the importance of having control over the creative process. ControlNet, a neural network model, offers us just that. This family of networks is based on Stable Diffusion, a powerful text-to-image generation model. However, ControlNet takes it a step further by adding a new layer of conditioning, which allows for more structural and artistic control over image generation.


Introduced in a research paper by Lvmin Zhang and Maneesh Agrawala, ControlNet is designed to learn very specific features related to the tasks it is being fine-tuned on. It can generate images from canny images, or even more complex ones like generating images from normal maps.


By training on a specific task, ControlNet can create more customized and unique images, allowing for greater artistic expression and control in the image generation process. Whether you are creating architectural models or visualizing interior designs, ControlNet can help bring your ideas to life with precision and creativity.



The authors fine-tune ControlNet to generate images from prompts and specific image structures. As such, ControlNet has two conditionings. ControlNet models have been fine-tuned to generate images from:


- Canny edge

- Hough line

- Scribble drawing

- HED edge

- Pose detections

- Segmentation maps

- Depth maps

- Cartoon line drawing

- Normal maps


These functions give us extra control over the images that we can generate.
